Loch is Scottish Gaelic in Origin.

Loch derives from Scottish Gaelic and Irish loch, meaning “lake” or a sea inlet comparable to a fjord. The term is central to Scottish toponymy (Loch Ness, Loch Lomond) and long ago passed into English usage; the final ch is the guttural sound of German Bach. Etymologically it continues Proto-Celtic *lokos and is cognate with Latin lacus and English lake, tying the name to the broader Indo-European family for bodies of water.

As a given name, Loch is a modern adoption in the English-speaking world, most visible in Scotland, Australia, New Zealand, and North America. It often serves as a clipped form of Lachlan (Gaelic Lachlann, “Scandinavia/land of lochs”), but also appeals as a gender-neutral nature name. Variants and related forms include Lockie/Lochie (diminutives), Lochlan/Lochlann, and the Irish toponymic spelling Lough. Similar-looking Locke is a separate English surname with a different origin.
