Roundstone (Irish: Cloch na Rón, meaning "seal's rock") is a village on the west coast of Ireland, in County Galway.
The town of Clifden is nearby to the north.
The anglicised name is usually considered an error on the part of the British colonial Ordnance Survey which translated the village name; while Cloch certainly means "stone" or "rock", Rón means "seal", not "round". Still, the names Cloch na Rón and Roundstone may be totally independent.
The bay is referred to as Round-stone Haven as early as 1684 (Roderick O'Flaherty), and the rock after which it is named stands like a marker at the entrance and is strikingly round.
Roundstone is known as a home for creativity and the arts. For many years some of the most important figures in Irish Art have painted there, including Paul Henry, Jack B. Yeats, Gerard Dillon and Nano Reid.
The Roundstone Arts Week celebrates youth and environment on an annual basis.
The local Summerfest, is held in July.
Traditional Irish Nights are held weekly throughout July and August and offers music, song and dance from the Connemara area.
