Ryan Anthony Williams (born 8 April 1991) is an English professional footballer who plays as a midfielder for AFC Eskilstuna. After beginning his career at Chester City, Williams came to prominence with Morecambe and built a reputation as a free kick specialist. He later played in Scotland, Canada, Brazil, the United States and won an international futsal cap for England.
 Born in Birkenhead, Williams came through the youth ranks at League Two club Chester City and a transfer embargo saw him and other youngsters promoted to the club's first team during the 2008–09 season at age 17. He was an unused substitute in seven matches between September and December 2008 and made his senior debut for the club in a 7–0 Cheshire Senior Cup semi-final defeat to Crewe Alexandra on 20 January 2009, but he tore ankle ligaments on the stroke of half time and failed to recover before the Seals' relegation at the end of the season.
 Williams signed for Northern Premier League First Division North club Colwyn Bay in late 2009. He helped the team achieve promotion to the Premier Division and moved to sign for Cymru Alliance club Llandudno on loan during the 2010–11 season, where his performances won him the club's Player of the Year award and a place in the league's Team of the Year. Williams transferred to fellow Cymru Alliance club Rhyl in July 2011 and was again voted into the Cymru Alliance Team of the Year at the end of the 2011–12 season. He departed Rhyl midway through the 2012–13 season.
 Williams began training with League Two club Morecambe in July 2012, but was not offered a contract due to financial constraints. After the departure of Joe Mwasile on loan, funds were made available for Williams to be offered a short-term contract with the Shrimps in October 2012.[citation needed] International clearance problems held up the signing and he finally joined the club on 10 January 2013. Williams made his Football League debut in a match versus Plymouth Argyle five days later, coming on as a 68th-minute substitute for Gary McDonald. He crowned his day with a long-range goal in the 80th minute, though the Shrimps would lose 2–1. He scored his second goal in three games versus Dagenham & Redbridge two weeks later, this time scoring a late winner in a 2–1 victory. A first start versus York City on 2 February and Man of the Match performances later in the month versus Exeter City and Aldershot Town saw Williams sign a new contract running until the end of the 2013–14 season. Williams made 16 appearances and scored two goals during the second half of the 2012–13 season.
 Williams was a regular starter during the 2013–14 season and got his campaign off to a flyer, netting long range goals with a free kick in a League Cup first round victory over Wolverhampton Wanderers and a 25-yard strike in a league draw with Torquay United. His performances saw him sign a new one-year contract extension in February 2014. Williams made 29 appearances and scored four goals during his first full season of league football and won Morecambe's Goal of the Season award. Williams began the 2014–15 season alternating between a starting berth and a place on the bench and missed the final two months of the season after undergoing surgery on a hernia problem. He finished the season with 16 appearances and no goals. Williams was released in May 2015 after making 61 appearances and scoring five goals during his two-and-a-half year spell at the Globe Arena.
 On 11 June 2015, Williams signed a one-year deal with Championship club Brentford, with the option for a further year. His only appearance for the Bees came with a start in a 4–0 League Cup first round defeat to Oxford United on 11 August. On 1 February 2016 and having failed to win a call into the squad in over four months, Williams' contract was cancelled by mutual consent. Get West London later reported that Williams "was a set-piece expert, but was never going to get in the first team and (Brentford) turned him into a set-pieces coach".
 On 1 February 2016, Williams joined Scottish Premiership club Inverness Caledonian Thistle on a contract until the end of the 2015–16 season. He made eight substitute appearances and was not offered a new contract at the end of the season.
