Loudon is Scottish in Origin.

Loudon is a transferred surname with chiefly Scottish and French place-name roots. In Scotland it refers to the parish of Loudoun in Ayrshire; scholars link the name either to Brittonic/Celtic elements meaning “fort of Lugh” (from the deity Lugh + dunon “fort”) or to Old English hlūd + dūn, “steep/loud hill.” A parallel origin comes from Loudun in western France, brought into English via Huguenot refugees, yielding the Anglicized form Loudon. Pronunciation is typically LOU-dən.

As a given name, Loudon emerged in the English-speaking world in the 18th–19th centuries through the common practice of adopting surnames and titles, helped by the visibility of the Earls of Loudoun and later by American usage (e.g., singer-songwriter Loudon Wainwright III). Variants include Loudoun, Louden, and Loudin; nicknames Lou and Don are possible. The name’s meanings converge around “hill-fort” or “Lugh’s fort,” giving it a sturdy, historic character.
