St Colman's College is an all-boys Catholic secondary school in Claremorris, County Mayo
The school was founded in 1945, as a school for the boys of Claremorris to attend instead of having to travel to Ballinrobe. An Old Manor House on the Knock Road was used as the site for the school, where it has remained to the present day. The school is named in honour of St. Colman, as Claremorris is in the parish of Kilcolman.
