MacLeod and McLeod ( /məˈklaʊd/) are surnames in the English language. Variant forms of the names are Macleod and Mcleod.
Generally, the names are considered to be Anglicised forms of the Scottish Gaelic MacLeòid, meaning "son of Leòd". However, in some cases the names can also be Anglicised forms of the Irish Mac Leóid. Another origin for the name, according to late 19th century Irish genealogist John O'Hart, is from the Irish Mac Giolla Mochadha (commonly Anglicised as MacGillicudy).
One of the earliest occurrences of the surname is of Gillandres MacLeod, in 1227. There are two recognised Scottish clans with the surname: Clan MacLeod, and Clan MacLeod of Lewis. The earliest record of a clan member from one of these two families, using a form of the surname MacLeod, occurs only as early as the 14th century.
