Oluwafemi Abayomi Alaba "Femi" Ilesanmi (born 18 April 1991) is an English professional footballer who plays as a defender for National League club Boreham Wood.

Ilesanmi started his career with AFC Wimbledon's youth system, making his first-team debut in 2007 before transferring to Queens Park Rangers in 2008, where he played for the under-18 team.

Ilesanmi spent four years with Dagenham & Redbridge before joining York City in May 2014, where he played for two seasons before being released.

[6][11] In February 2010, he signed for Isthmian League Premier Division club Ashford Town (Middlesex), where he spent a short spell.

[10] The trial was successful and Ilesanmi signed a two-year contract with the newly promoted League One club in July 2010.

[19] His final match for Histon came in a 1–1 draw with Wrexham on 30 October, where he provided the assist for a stoppage time equaliser.

[22] This persuaded him to hand Ilesanmi a surprise professional and league debut for Dagenham in a 1–0 defeat to Oldham Athletic, where he played in place of Damien McCrory.

[citation needed] He received his first red card for Dagenham in March 2011, in a 1–1 draw with Leyton Orient when he brought down Paul-José M'Poku to concede a late penalty.

[27] Ilesanmi started 2011–12 as understudy to Damien McCrory, making his first appearance of the season in the League Cup, a 5–0 defeat to AFC Bournemouth.

[30] This proved to be his final appearance of the season, as Dagenham narrowly escaped successive relegation's to the Conference Premier.

[35] Dagenham again narrowly avoided relegation to the Conference, this time on the final day of the season, despite losing 1–0 to York City.

[citation needed] He started in Wayne Burnett's first match in full charge of Dagenham, a 3–1 away defeat to Fleetwood Town.

[38] Having made 32 appearances in 2013–14,[39] Ilesanmi was released by Dagenham in May 2014, with Burnett saying "it was also the right time for him to move on, he's been a fantastic servant for this football club and I wish him every success".

[43] Ilesanmi joined National League club Boreham Wood on 5 August 2016, and was an unused substitute the following day in their 1–0 home win over Forest Green Rovers.

[47] On 27 June 2017, Ilesanmi signed for National League club Dover Athletic on a one-year contract.
