Coolock (Irish: An Chúlóg, meaning "The Little Corner") is a large suburban area, centred on a village, on Dublin city's Northside in Ireland. Coolock is crossed by the Santry River, a prominent feature in the middle of the district, with a linear park and ponds. The Coolock suburban area encompasses parts of three Dublin postal districts: Dublin 5, Dublin 13 and Dublin 17.
