Harry Anthony Hall Williams, (born 1 October 1991) in London, England, is an English international rugby union player.

Williams previously played for London Wasps, Nottingham, Jersey Reds, Exeter Chiefs and Montpellier Hérault Rugby.

[1] He later attended Whitgift School, where he played alongside future England internationals Elliot Daly, Marland Yarde, and George Merrick.

[2][9] In April 2015, Harry Williams left Jersey for Exeter[10] as he wanted to play at the highest level with an ambitious club.

[15] Williams was a starter, playing for 50 minutes and celebrating the first title of his career, although he did not participate in the 2016–17 Anglo-Welsh Cup final against Leicester, which they lost.

[19] After three international tests in November 2017, he was selected in January 2018 to compete in the Six Nations Championship, during which he played in three matches against Italy, Wales, and Scotland.

He played a friendly against Wales in preparation but was not included in the World Cup squad, as Eddie Jones opted for Kyle Sinckler and Dan Cole in his position.

[30] Williams made his debut on 2 December 2023 at Stade Jean-Dauger, entering the game as a substitute for Titi Lamositele in the 53rd minute against Aviron Bayonnais.
