The Alleged Stakes is a Group 3 flat horse race in Ireland open to thoroughbreds aged four years or older.
It is run over a distance of 1 mile and 2 furlongs (2,012 metres) at the Curragh in April.
The race is named in honour of Alleged who was trained by Vincent O'Brien to win the Prix de l'Arc de Triomphe in 1977 and 1978.
The 2017 running commemorated the centenary of O'Brien's birth.
It was upgraded from Listed status to Group 3 in 2017.
