The meaning of the name Hogan is "Descendant Of The Young Warrior". The origin of the name Hogan is Irish.
Hogan is an Irish surname derived from Irish Ó hÓgáin, a patronymic of Middle Irish ógán, meaning "a youth", in the genitive case (cf. Modern Irish ógánach), itself from óg, "young" (ultimately cognate with English young), with a prothetic h. A surname of the same form was Anglicised as "Hagan" in Northern Ireland. Some southern bearers claim descent from an uncle of Brian Boru, High King of Ireland (–). Occasionally appears as an absorption of west Connacht (O')Houghegan (Irish: Ó hEochagáin). Hypothetically derivable from related words in Cornish and Welsh.
