Eachann is a masculine given name in Scottish Gaelic. A similar and possibly related early form of the name was Eachdonn. The name is composed of two elements; the first element is each, meaning "horse". The second element is donn, which has been given two different meanings. One proposed meaning is "brown"; another proposed meaning is "lord". The early Gaelic form of the name, Eachdonn, was 'confused' with the Norse Hakon.
