Jonathan Peter Williams (born 9 October 1993) is a professional footballer who plays as a midfielder for EFL League Two club Gillingham.

Williams started his career at Crystal Palace, and whilst there had loan spells at Nottingham Forest, Milton Keynes Dons, Ipswich Town and Sunderland.

Williams made his breakthrough into the Crystal Palace first team at the beginning of the 2011–12 season, after much hype surrounding his performances for the academy and reserve side the previous term.

[4] One week later, Williams made his full first-team debut in the opening game of the 2011–12 League Cup, at home to Crawley Town.

[citation needed] He scored his first professional goal for Crystal Palace on 13 September 2011, in a match against Wigan Athletic in the League Cup.

After he recovered from the injury he started against Preston North End in a League Cup tie,[7] and then came on as a substitute on 1 September against Sheffield Wednesday, Palace's first win of the season.

[8] Williams' efforts after making a comeback from the injury were rewarded when he received Crystal Palace's Young Player of the Year award for the season.

[12][13] Having suffered a groin injury in early November, Williams made only five appearances for Ipswich, scoring one goal, before his return to Palace at the beginning of January 2015 once the loan spell ended.

[14] On the emergency loan deadline day in March 2015, Williams re-signed for a third spell at the Suffolk side (along with Zeki Fryers) until the end of the season.

Williams was called up to the senior Wales squad on 3 October 2011, by then manager Gary Speed, following injuries to three players for the matches against Switzerland and Bulgaria.

On 29 August 2012, Williams was again called up to the Wales senior squad by manager Chris Coleman for the World Cup qualifiers against Belgium and Serbia.

[31] On 22 March 2013, Williams made his international debut in a 2–1 victory over Scotland when he appeared as a substitute at half time in place of Gareth Bale.
