Lock is an English surname-turned-given name with several roots. From Old English loc/locc, it denoted a lock or fastening and, by extension, a “lock of hair,” yielding either an occupational surname for a locksmith or a nickname for someone with notable curls; in some cases it marked residence near a lock-gate. A separate Scottish/Irish route makes Lock a clipped pet form of Lachlan/Lochlan (from Gaelic Lochlann, “land of lochs/fjords,” historically referring to Scandinavia).

As a first name it appears sporadically in Britain and North America from the 18th century, typically adopted from a family surname or in learned homage to the philosopher John Locke (whose spelling with -e also persists). Variants and related forms include Locke, Locky/Lockie, Loch, Lok, and the fuller Lachlan/Lochlan; feminine or unisex short forms such as Lockie also occur in modern use.
