What is the meaning of the name Lachlan ?

The baby name Lachlan is a Male name , 2 syllables long and is pronounced /ˈlæk.lən/ (LAK-lən),Scottish Gaelic: /ˈlax.lən/ (LAKH-lən or LOCH-lən, with a guttural 'ch').

Lachlan is Scottish Gaelic in Origin.

Lachlan is the Anglicized form of Scottish Gaelic Lachlann, ultimately from the Gaelic place-name Lochlann, a medieval term for Scandinavia (“land of lochs/fjords”). In Gaelic use it referred to a Norseman or someone from the fjord-lands, so the name is often taken to mean “from Scandinavia” or “Viking,” with a parallel folk reading of “land of lakes.”

The name flourished in the Scottish Highlands during Norse-Gaelic contact and persisted in clan circles; a noted bearer is Lachlan Mòr MacLean, 16th-century chief of Clan MacLean. Carried by emigrants, Lachlan became especially popular in Australia and New Zealand from the late 20th century, and it remains well used across the English-speaking world. Variants include Lachlann (Gaelic), Lochlainn (Irish), Lochlan, and Lauchlan; diminutives and spellings include Lachie, Lachy, and Lockie. Related surnames derived from the personal name include McLachlan and MacLachlan.
