Larkin is from Ringsend and played youth football for the local team Cambridge FC.[2] At nine years old Larkin was accepted into The Metropolitan Girls League Academy two years earlier than the usual admission age of 11.[3] She also played at youth level for Home Farm, before joining Shelbourne.[4]
Shelbourne announced that Larkin had signed for another season at the end of a successful 2022 Women's National League campaign, in which she helped the club secure a League and Cup double.[11] However they were disappointed when Larkin subsequently experienced "a change of heart" and instead moved to newly-reformed Shamrock Rovers alongside some other Shelbourne players. A controversial and swiftly-deleted tweet on the Shelbourne club account, referencing The Red Flag lyrics 'Though cowards flinch and traitors sneer', was perceived as being aimed at the departing players and attracted "huge criticism",[12] particularly given Larkin's youth.[13]
In September 2023, Larkin joined Glasgow City.[14] She scored nine goals in sixteen matches across all competitions, before moving to Crystal Palace in January 2024.[15][16]
Larkin was called up to the senior Republic of Ireland squad for the first time in February 2022, for the 2022 Pinatar Cup in Murcia.[19] She required her parents' permission to miss school for the trip.[20] She won her first cap on 19 February 2022 in a 1–0 defeat by Russia[2] and appeared as a half-time substitute for Kyra Carusa in a 1–0 win over Wales.[21]
On 27 June 2022, Larkin scored her first goal for Ireland on the occasion of her fourth cap, in a 9–0 World Cup qualification win over Georgia in Gori. CoachVera Pauw was impressed by Larkin's impact: "She's only 17-years-old, but I hope that everybody has seen how talented she is."[22]
In July 2023, Larkin was selected in the 23-woman squad for the 2023 FIFA Women's World Cup.[23] She made her World Cup debut in the 1–0 loss to co-hosts Australia, coming on as a substitute for Sinead Farrelly,[24] and in doing so, became the youngest player (male or female) to represent the Republic.[25] She would go on to make two more substitute appearances, as the Republic finished bottom of their group with one point.[26][27]
Personal life
One of Larkin's cousins is fellow professional footballer Daniel Kelly, who plays for Derry.[28]
