Mark Sykes (born 4 August 1997) is an Irish professional footballer who plays as a midfielder for EFL Championship club Millwall.
Born in Northern Ireland, he plays for the Republic of Ireland national team, having previously represented Northern Ireland at underage level.
Born in Belfast, Sykes began his career with Glenavon. In December 2017 he was linked with a transfer away from the club. In February 2018 he signed a new contract until the end of the 2018–19 season. In March 2018 he was described by a journalist as "one of the most outstanding young prospects in the Irish League".
In January 2019 he signed for English club Oxford United, making his debut on 8 January 2019 in the EFL Trophy. He scored his first goal for Oxford against Millwall in the EFL Cup on 27 August 2019, and his first league goal in a 2–1 victory over AFC Wimbledon on 29 December 2019. In his three and a half seasons at the club he made 137 appearances and scored 12 times, including Oxford's consolation goal in their 2–1 defeat to Wycombe Wanderers in the 2020 EFL League One play-off final at Wembley Stadium.
In May 2022, Bristol City announced that they had signed Sykes, with the transfer becoming official on 1 July 2022, on a three-year deal with the option of a further year. On 3 October 2023, Sykes was voted Bristol City's September Player of the Month, receiving 46% of the total votes. On 2 February 2025, Sykes signed a 12 month contract extension. On 12 June 2026, it was announced that Sykes would be released at the end of his contract.
On 9 July 2026, Sykes joined Millwall on a two-year deal.
Sykes has also played for Northern Ireland at under-18, under-19 and under-21 youth levels. He made his debut for the under-21 side in September 2016, in a 2–0 defeat to Macedonia and as of 28 January 2019 had 11 caps and 2 goals.
He received his first call-up to the Northern Ireland senior team in May 2019. He was called up again in September 2019.
In August 2020, Sykes informed the Irish Football Association (which governs football in Northern Ireland) that he no longer wished to be considered for their squad, instead opting for the Republic of Ireland. In March 2022, he was named in Stephen Kenny's Republic of Ireland squad for forthcoming friendly matches.
Sykes was named as a late inclusion to the squad in November 2022 for the Republic of Ireland's November friendlies with Norway and Malta, following the withdrawals of two players through injury.
On 20 November 2022, Sykes made his debut in a 1–0 win over Malta, becoming the first Belfast–born player to represent the Republic of Ireland since 1946.
