Kaherdin is Gaelic in Origin.

Kaherdin is a rare masculine name of Brythonic (especially Breton) pedigree, best known from the Tristan and Iseult cycle. It appears in 12th–13th‑century romances - Thomas of Britain and Béroul’s Tristan poems, Gottfried von Strassburg (as Kahedîn), and the Prose Tristan - where Kaherdin (often the brother of Iseult of the White Hands) is a close companion of Tristan. The name survived in literary tradition but saw little use as a given name until modern times.

Its etymology remains debated. Scholars have proposed Brythonic elements such as caer/ker “fort” and din “fort, hill-fort,” or links to cad “battle,” yet none is demonstrably conclusive, so the meaning is best treated as uncertain. Documented variants include Kahedin, Kahédin (French), Kahedîn (scholarly Germanized form), and Kehedin. Contemporary use is concentrated in Brittany and France, where cultural revival has prompted occasional, though still very rare, adoption.
