Scottish Gaelic literature refers to literary works composed in the Scottish Gaelic language, which is, like Irish and Manx, a member of the Goidelic branch of Celtic languages. Gaelic literature was also composed in Gàidhealtachd communities throughout the global Scottish diaspora where the language has been and is still spoken.
