Lachy

Lachy is a masculine given name and nickname, primarily used in Australia and New Zealand. It is most commonly a diminutive form of Lachlan, though it can also be given as a stand-alone name.

The name Lachlan is of Gaelic origin, from Lachlainn, and is often linked to the landscape of Scotland, with associations to the lochs or lakes. As a diminutive, Lachy shares the same roots and is valued for its informal, friendly tone.

In everyday use, Lachy functions as a casual form of Lachlan among family and friends and may be used as a stand-alone given name in its own right. Spelling variants include Lachie as well as Lachy, with pronunciation that tends to be straightforward in Australian English.

Notable people known by the nickname Lachy include Lachy Doley, an Australian musician who performs under that name. The nickname Lachy reflects broader Australian naming practices that favor shortened, affectionate forms, and it remains a recognizable informal variant within contemporary Anglophone naming.
