In August 2015 Tipuric named to the Welsh national rugby union team 47 man training squad for 2015 Rugby World Cup, and started in the home & away warm-up fixtures against Ireland, scoring tries in both fixtures (the first was nominated for World Rugby Try of the Year) and being named man of the match in the second game. Tipuric was named to the final 31 man squad, and despite his fantastic form entering the tournament, he was dropped from the starting XV in favour of returning captain Sam Warburton. He did however feature in all 5 of Wales' games scoring a try in the win 54-9 against Uruguay national rugby union team, his third successive international with a try.
