Roundstone (Irish: Cloch na Rón, meaning 'seal's rock') is a village on the west coast of Ireland, in the Connemara region of County Galway.

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.

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.

Traditional Irish Nights are held weekly throughout July and August and offers music, song and dance from the Connemara area.
