Leachlainn is Irish, Scottish Gaelic in Origin.

Leachlainn is a Gaelic given name, a variant spelling of Lochlainn/Lachlann found in Irish records. It derives from the Gaelic toponym Lochlann, the traditional Gaelic name for Scandinavia, literally “land of lochs/lakes,” and by extension denotes a “Norseman” or “man from Scandinavia.” Phonetically, it is close to Lachlann (roughly LAKH-lin, with ch as in German Bach). The form Leachlainn reflects older or regional orthography, keeping the same sense and pronunciation family.

The name was widely used among medieval Irish and Scottish Gaels, appearing in annals and borne by nobles; it lies behind surnames such as Mac Lochlainn/MacLachlainn, later anglicized McLoughlin and MacLachlan. Modern given-name variants include Lochlann, Lachlann, Lochlan, and Lachlan, with pet forms Lachie and Lockie; Irish Anglicized forms include Loughlin and Laughlin. Today Leachlainn is rare but retains strong cultural resonance in Ireland and Scotland alongside the popular Lachlan.
