Collooney railway station serves the town of Collooney in County Sligo, Ireland. Collooney once had three railway stations. The current station was opened by the Midland Great Western Railway (MGWR) on 3 December 1862 as part of the extension of its line from Longford to Sligo. On 1 September 1881 the Sligo, Leitrim and Northern Counties Railway (SL&NCR) opened its station to the east, before building a connection to the MGWR at Carrignagat Junction to the north and thus completing its line from Enniskillen to Sligo. Finally, on 1 October 1895, the Great Southern and Western Railway (GS&WR) opened its station to the west, as part of the extension of its line from Claremorris to Sligo.
