Torsa (occasionally Torsay) is one of the Slate Islands in Argyll and Bute, Scotland. Lying east of Luing and south of Seil, the island was inhabited until the 1960s. There is now only one house on the island, which is used for holiday lets. Its main industry is farming, with cattle brought over from the neighbouring island of Luing. The Luing cattle were bred for their hardiness.
