Viewers will be able to watch Wales’s three pool matches, against Ireland, Georgia and England, and their fourth game on the Finals weekend, live on the Welsh language free-to-air channel, after the broadcaster reached an agreement with Six Nations Rugby Ltd.
The competition gets underway on Friday 13 November, when Ireland host Wales at the Aviva Stadium, in Dublin.
S4C will also have live coverage of the friendly match between France and Wales on Saturday 24 October, and Wales’s 2020 Guinness Six Nations finale against Scotland, on Saturday 31 October.
Sue Butler, S4C Sports Commissioner, said: “We are delighted that viewers can follow Wales in this exciting new competition live on S4C.
“As a longstanding broadcast partner of the WRU, this agreement reaffirms S4C’s commitment to providing high-quality rugby coverage in the Welsh language for all Welsh rugby fans.”
Craig Maxwell, WRU Commerical Director, said: “S4C continue to be a great supporter of Welsh rugby. This deal is great for fans as it means they can watch our exciting Autumn Nations cup fixtures in the Welsh language”
