Meaning & origin
Mckoy entered the U.S. baby name charts in 1999, a modern respelling of the Irish surname McCoy. Its peak popularity came in 2019, and since 2020 its usage has been on a gradual decline. As of 2025, it sits at rank 5,399 with roughly 1 in every 100,475 newborns receiving the name. While it has not been widely adopted in any specific state, its rarity gives it a distinctive sound. Mckoy fits into a broader trend of surnames used as first names, particularly those ending in the 'oy' sound, though it remains far less common than related names like McCoy or Mackoy.
Mckoy is a rare given name that likely derives from the Irish surname McCoy, an anglicized form of the Gaelic Mac Aodha, meaning 'son of Aodh' (Aodh being an ancient Irish god of fire and the sun, later a personal name meaning 'fire'). The spelling Mckoy, with a lowercase 'c', is a modern respelling that emerged in the late 20th century. The name has been in limited use as a first name in the United States since the late 1990s, primarily for boys.
