Founded in 1886 as Flint F.C; playing at Strand Park which was located on the banks of the Dee Estuary. The club made an early impression by reaching the first Welsh Amateur Cup final in 1890-9, losing to Wrexham Victoria 4-1.
Founder members of the North Wales Coast League the club won the inaugural championship in 1893-94 by two points over runners-up Llandudno Swifts, remaining unbeaten in their twelve games. The next two seasons the club finished in the runners-up position before resigning from the league to join the newly formed Flintshire League.

By the turn of the century the town of Flint had three teams; Flint Town, Flint Athletic and Flint UAC (United Alkali Company) In 1905, Flint UAC and Flint Town amalgamated, taking the name of Flint Town. In 1909, as a Chester and District League side the club won their first major cup by defeating Pwllheli 1-0 in the final of the North Wales Amateur Cup.

In 1924 the club left Stand Park for a new ground at Holywell Road, which was become their home till 1993. The new ground was then better equipped and could hold up to 3000 spectators. These size of crowds were common in the 1920s, they were keen to see Flint’s part time professionals play. Led by Captain Emlyn Jones, Flint reached the 1925 Welsh Cup final only to lose to Wrexham’s professional team by 3 goals to 1. Regular cup success’s were to follow however, as Flint won the North Wales Amateur Cup on three occasions between 1931 and 1932.

Flint Town featured in the Welsh National League (North) throughout the 1920s, becoming runners-up to Owestry Town in 1923/24 season. In 1930 Flint Town joined the newly formed Welsh League which operated between 1930 and 1935, winning the title in 1933/34 season, scoring 99 goals in only eighteen games, and being runners up in the following season.

Between 1937 and 1949, apart from the war years, Flint Town played their football in the West Cheshire League, while Flint Athletic continued to play in the Dyserth League winning the title in 1938 and 1939.

Following the Second World War, the amalgamation of Flint Town and Flint Athletic football clubs resulted in the formation of the club bearing the title Flint Town United Football Club which entered the Welsh League (North) for the 1949-50 season, finishing runners-up to Holyhead Town. By this time, however, the club had already won the Welsh Amateur Cup, having defeated Troedyrhiw 2-1 in the 1947-48 final.
Under the managership of Billy Russell Flint became a formidable side in the early 50s, with the pinnacle achievement coming in 1954 when they won the Welsh Senior Cup. Inspired by Welsh International Billy Hughes, whose career was disrupted by the war, overcame Holywell Town, Owestry Town, Rhyl, Llanelly and a semi-final 2-1 win over First Division Cardiff City, in front of a crowd of 10,683 at the Racecourse, Wrexham, beating third division Chester City 2-0 in the final, again at the Racecourse Ground Wrexham in front of a crowd of 15,584. During this period, they also won the League title in three consecutive seasons and were runners up on two occasions.
Within five years of those golden seasons the club slipped into the lower reaches of the league culminating in relegation at the end of the 1961-62 seasons.
During the 60s the crowds of past years disappeared, bringing a decline in the club’s fortunes. Now playing in local leagues the club relied on local players. The only bright spots in this decade were Flint Town Utd Youth winning the Welsh Youth Cup in 1965 and the Welsh Amateur Cup in 1969.
During the 1970s and 80s the club moved between various leagues, becoming league champions of the Clwyd League in 1978/79 and Welsh League (North) in the 1988-89 season.

1990 saw the transformation of Welsh Football with the formation of two new leagues. The Cymru Alliance was formed to incorporate teams playing in the Welsh League (North), Welsh National League (Wrexham), Clwyd League and the Mid-Wales League.
In that same season the club appointed Tony Martin as their new manager, with Les Davies his assistant. That season saw the club become the inaugural champions of the new league, whilst also winning the North Wales Challenge Cup for the first time in the clubs history.
To cap an excellent season they overcame South Wales Champions Abergavenny 2-1, to become the non-league champions of Wales.

In 1992, Fint became founder members of the League of Wales (LOW). The following season the club again moved to a new ground, back to its original home on the the banks of the Dee Estuary. After six years in the League of Wales, with a fourth place finish (1993/94) being our highest placing during this time, and with finances becoming an increasing burden with no main sponsors, the club eventually lost it’s place when it finished third from bottom (being relegated due to the LOW reducing the number of teams within the league under UEFA rules), rejoining the Cymru Alliance League.

In 2000/01, we suffered the ignominy of finishing bottom of the table, having been handed a nine point deduction. Fortunately no relegation followed, and for the next couple of seasons we finished in a respectable mid-table berth.
For the 2005/06 season the club produced a remarkable recovery with local lad Paul Davies joining Dai Beck as part of the managerial team. Davies had enjoyed considerable success as a manager in the Deeside Sunday League over the years.The season got off to a good start with a home win, but inconsistency became a regular occurrence. That was until Saturday 22nd October 2005 when a bad defeat at the hands of Ruthin Town turned the clubs fortunes around, going 25 leagues games without defeat, the only blip being beaten by Denbigh Town in the N.W Challenge Cup. The club missed out on promotion to the Welsh Premier League by four points, having had a three point deduction for a non-fulfilment of a mid-week fixture at Gresford Athletic, and we eventually finished in third place.
For the 2006/07 season the club was again hardly out of the top three, but a bad run of results in March, picking up only three points out of five games and then another bad run, three points out a possible twelve late on in the season put the League Championship out of reach, finishing third once more. Consolation was winning the North Wales Challenge Cup at Colwyn Bay, beating league rivals Prestatyn Town 1-0.

The following season (2007/08) saw an up and down league and cup performance, but in April a six match unbeaten run moved the club into third position in the league, for a third consecutive season. In the last game of the season another one of those poor performances returned when the club was well beaten by fellow Cymru Alliance club Llandudno Town 4-1 in the final of the North Wales Challenge Cup, to end the season on a disappointing note.

With the reformation of the Welsh Premier League set for the 2010-11 season the club’s sole intention for the 2009-10 season was to finish in the top eight. However, as the season drew to a close we were nine points clear at the top of the table, following a memorable 5-1 home win over rivals Llangefni, all the more remarkable as we were reduced to nine men for the entire second half. However, in the last four league games we only managed to pick up only five points out of a total of 12, losing the league to the Anglesey side by four points. In the final game of the season the club lost to Llandudno Town 2-0 in the League Cup Final, with Llandudno’s keeper, Paul Whitfield picking up the “Man of the Match Award”.

2010-11 season starts of with a defeat at the hands of newcomers Rhos Aelwyd 2-1, followed four weeks later by a defeat in the League Cup at home to Porthmadog 2-1. At the start of October a another disastrous defeat this time in the Welsh Cup, losing 4-3 at home to mid Wales team Llanidloes Town. The league was an up and down affair, but we enjoyed a good run in the North Wales Challenge, reaching the final only to lose on penalties, leading goal scorer Shaun Beck missing the only penalty.

Mid table mediocrity tended to be the template for the next few seasons, but in 2012-13 we did reach the quarter final of the Welsh Cup, only to lose 2 nil at home to Barry Town, in what was a very disappointing performance by us on the day. The final game of the season offered one last chance for silverware as we faced neighbours Buckly Town in the final of the North East Wales Challenge Cup, only the second time the club had ever played in this competition. The game was played at The Racecourse, Wrexham in front of a large crowd, but again finishing was our undoing, losing 2-1 in normal time.
The League Cup final was reached in 2013-14, where we faced Caernarfon Town. Unfortunately, on the day, the Canaries proved to be the stronger side, and ran out 3-1 winners.
2014/15 saw no less than three managers take charge. Paul Davies, after 10 years in charge, stepped down from being the 1st Team manager, and became the club's first Director of Football. His Assistant, Howard Tweats, who had joined in the close season, was appointed Interim First Team Manager. But after some indifferent results, including a Welsh Cup defeat at the hand of Penrhyncoch, Tweats left by mutual consent. Timmy Williams took over the reins, and overcame an extremely poor start, by being awarded manager of the month for January. Results on the pitch had followed a similar pattern to previous years, with inconsistency the order of the day. Williams stepped down from the managerial position at the end of the season.
It was off the field matters which took precedence, as thanks to the hard work of a dedicated few, the club was finally awarded the domestic licence, a pre-requisite for promotion back to the Welsh Premier League, and it is something we have proudly attained for each of the following seasons.
At the start of 2017/18, former Everton & Hibernian coach and local Flint lad, Andy Holden was appointed manager. However, the switch from coaching full time professionals to players at a semi-professional level, proved problematic, and after a series of indifferent results, Holden decided to step down. Ex-Rhyl manager, Niall McGuinness, was subsequently appointed, and after a slow start, results improved, and some momentum was gained. Once again we reached the final of the League Cup, and at the sixth time of asking, we finally won the cup, beating Gresford Athletic in a sudden death penalty shoot out.
Greater consistency in the league was rewarded by a runners up position for season 2018/19, and this feat was repeated for 2019/20, a season abruptly curtailed by the Covid 19 outbreak. Champions Prestatyn Town were refused promotion to the JD Cymru Premier League, following their failure to secure the Tier 1 Licence. Consequently, we were accepted into the Premier League, having successfully gained the licence. So, after an absence of 22 years, we were finally back in the top tier of Welsh domestic football.
Our return to the top tier for Season 2020/21, was somewhat muted and a surreal atmosphere prevailed, with games having to be played behind closed doors due to the ongoing pandemic, and the season being a stop/start affair due to lockdowns. A reasonably bright start was soon a distant memory, as we underwent a wretched run of 10 defeats in 11 games, including a 10-0 thrashing at The New Saints. A 6-3 defeat away at Barry, proved the final straw, and Niall McGuinness departed the club and was replaced by former Prestatyn manager, Neil Gibson, who was given the brief to ensure the club finished outside of the bottom two, so as to guarantee it's Cymru Premier status, should Tier 2 football resume as planned.
In the event, the worsening Covid situation put paid to the resumption of Tier 2 football in Wales, and Flint were spared relegation, despite finishing in 11th place (next to bottom) in the final table, in what was an arduous and mentally exhausting season for all concerned.
Now, having had the close season to prepare and assemble his squad, and with a whole set of league fixtures ahead, Neil Gibson and his staff will be doing their utmost to make sure we do not find ourselves in the same predicament once again.
