Mclean is an uncommon, unisex given name of Scottish origin. It is derived from the Scottish surname MacLean, which is composed of two Gaelic elements: 'Mac' meaning 'son of', and 'Leàinn' referring to a speaker of Irish Gaelic. The name was borne by many Highland clansmen, including several notable chiefs of the Clan Maclean. In recent times, Mclean has been used independently as a given name, often spelled with or without the initial 'M'. Notable individuals named Mclean include American basketball player McLain Brown and Canadian hockey player Mike McLean.
"The name McLean experienced a notable increase in popularity from the mid-80s to the late 90s, peaking with 16 births in 1996 and remaining consistently high until the early 2000s. However, it has seen a decline since then, with the most recent years showing a steady state of around 5 to 7 births annually."
