Conor John Gallagher (born 6 February 2000) is an English professional footballer who plays as a midfielder for Premier League club Tottenham Hotspur and the England national team.
Beginning his career with Chelsea, Gallagher spent time on loan at EFL Championship clubs Charlton Athletic, Swansea City, and Premier League clubs West Bromwich Albion and Crystal Palace, between 2019 and 2022. At Crystal Palace, Gallagher was named the club's Player of the Year for the 2021–22 season. He subsequently made his first-team debut at Chelsea in the following campaign, spending two seasons with the first team before joining Atlético Madrid in 2024. He returned to England after 18 months, signing with Tottenham Hotspur in January 2026.
After representing England at various youth levels, Gallagher made his debut for the senior national team in November 2021. He was a member of England's squad at both the 2022 FIFA World Cup and UEFA Euro 2024.
Gallagher was born in Epsom, Surrey to Lee and Samantha Gallagher and is the youngest of their four sons. He grew up in Great Bookham and attended Howard of Effingham School. His older brothers, Jake, Josh and Dan, are footballers at non-League level. Gallagher's family are Chelsea fans, and he lived a ten-minute drive from their training ground in Stoke d'Abernon. He is of Irish descent through his father, and Scottish descent through his maternal grandfather.
In June 2026, Gallagher announced his engagement to Aine May.
After playing for grassroots teams Bookham Colts, Leatherhead Predators and Epsom Eagles, Gallagher joined Chelsea at the age of six. In October 2018, he signed a new contract with Chelsea, contracting him to the club until June 2021. He had minor heart surgery that year. In May 2019, he was an unused substitute in the 2019 UEFA Europa League final, collecting a winner's medal. He was awarded Chelsea's Academy Player of the Year for the 2018–19 season.
2019–20 season: Loans to Charlton Athletic and Swansea City
In August 2019, Gallagher signed a new three-year contract with Chelsea and moved on loan to Championship club Charlton Athletic. After his first month with Charlton, in which he scored three goals in six matches, he won the EFL Young Player of the Month award for August. On 14 January 2020, Gallagher was recalled by Chelsea.
On 15 January 2020, the day after leaving Charlton, Gallagher joined Championship club Swansea City on loan for the rest of the 2019–20 season. During his time in South Wales, Gallagher was part of the Swansea team that reached the semi-finals of the Championship play-off, where they lost 3–2 to Brentford on aggregate. He later said that his time at Swansea allowed him to be more creative as a player.
2020–21 season: Loan to West Bromwich Albion
On 17 September 2020, Gallagher signed a new five-year contract with Chelsea, and joined fellow Premier League club West Bromwich Albion on loan for the 2020–21 season. On 28 November, Gallagher scored his first Premier League goal and his first goal for West Brom in a 1–0 home league win over Sheffield United. His only other goal for the club came in a 5–1 home defeat to future club Crystal Palace on 6 December.
Gallagher was named Albion's Young Player of the Season as the club finished 19th in the Premier League and were relegated to the Championship.
2021–22 season: Loan to Crystal Palace
In July 2021, Gallagher joined Premier League club Crystal Palace on loan for the 2021–22 season. He scored two goals in a 2–2 draw with West Ham United on 28 August 2021, his first goals for Palace. In November, Gallagher was subjected to homophobic chants from a group of Leeds United fans; the club issued a statement which condemned this. By the start of December, he had six goals and three assists for Crystal Palace, the most of any Premier League player aged 21 or under. On 15 April 2022, he was prevented by parent club Chelsea from playing against them in the FA Cup semi-final; Chelsea manager Thomas Tuchel apologised for doing so. Chelsea went on to defeat Palace 2–0.
During his season with Palace, Gallagher was described by The Daily Telegraph as "one of the Premier League's most vibrant talents" and "a key player for Patrick Vieira", who was "thriving in his box-to-box role". For his performances with the club, he was later named Crystal Palace's Player of the Season.
2022–23 season: Return to Chelsea
In July 2022, ahead of the 2022–23 season, Gallagher said he was determined to make a first-team breakthrough at Chelsea.
On 6 August 2022, he made his Chelsea debut as a substitute in a 1–0 away win against Everton in the Premier League.
