Kimmage (Irish: Camaigh) is a small residential suburb located on the south side of Dublin, Ireland. Surrounded by Crumlin, Greenhills, Harold's Cross, Rathfarnham, Templeogue and Terenure, the name Kimmage comes from the Irish Gaelic cam uisce, which means winding water. In this case it is the water of the River Poddle, a Liffey tributary, which provided the major water supply to medieval Dublin. Rising at Tymon Lake near the Green Hills, it flows through Kimmage, and north to the city after dividing at Mount Argus. One stream flows through via Crumlin and Dolphins Barn to join the River Liffey after Mullinahack, a millrace near Usher's Island. The other stream flows via The Coombe underground around Dublin Castle and into the Liffey further east near Merchants Quay.
