Neco Shay Williams (born 13 April 2001) is a Welsh professional footballer who plays as a full-back for Premier League club Nottingham Forest and the Wales national team.

[9][10][11] He suffered a serious back injury that ruled him out for most of the 2017–18 season, but he recovered his place to feature in the club's victorious FA Youth Cup campaign two years later.

[12] Williams' form at youth level was rewarded when, on 30 October 2019, he made his debut for the senior side, starting in a 5–5 (5–4) penalty shoot-out win over Arsenal in the EFL Cup.

[15] Following the turn of the year, he starred in a team largely made up of teenagers and reserves that defeated Merseyside rivals Everton in the FA Cup 3rd round, and Shrewsbury Town in the 4th round replay, forcing an own goal from Ro-Shaun Williams in the latter fixture to secure his side's progression in the competition.

[16][17] In the match against Shrewsbury, Williams was also part of a starting line-up that was the youngest in Liverpool's history, with an average age of 19 years and two days.

[18] His Premier League debut followed on 24 June 2020, shortly after the campaign resumed following a three-month long suspension caused by the COVID-19 outbreak, when he featured as a 74th-minute substitute in a 4–0 win over Crystal Palace.

[24] Williams signed for newly promoted Premier League club Nottingham Forest on 10 July 2022 on a four-year contract for a fee reported to be around £17 million.
