Ewen MacLachlan (Gaelic: Eòghann MacLachlainn)[1] (1775[2]–1822) was a Scottish scholar and poet.
MacLachlan was born in Lochaber, and educated at Aberdeen University.
He translated the first eight books of Homer's Iliad into Gaelic.
He also composed and published his own Gaelic Attempts in Verse (1807) and Metrical Effusions (1816), and contributed greatly to the 1828 Gaelic–English Dictionary.
In 2021, Ionad Eòghainn MhicLachlainn (The National Centre for Gaelic Translation) was founded at the University of Aberdeen, to promote and enhance translation out of and into Gaelic, and was named in MacLachlan's honour.
