Roscommon is the county town and the largest town in County Roscommon in Ireland. It is roughly in the centre of Ireland, near the meeting of the N60, N61 and N63 roads. The town is in a civil parish of the same name. The name Roscommon is derived from Coman mac Faelchon who built a monastery there in the 5th century. The woods near the monastery became known as Ros Comáin. This was later anglicised to Roscommon. Its population at the 2022 census was 6,555.
