The surname Sheehan is an Irish-Gaelic surname found mainly in the province of Munster in Ireland. Spellings and variants of the surname include O’Sheehan, MacSheehan, McSheehan, Sheenan, Shean, and Sheehan.

The surname is derived from the Gaelic name O'Siochain, a patronymic alias of the Old Gaelic personal name Siochad. The root word of the name is ‘sioch’, which is a Gaelic term meaning ‘peaceful’.

The name was historically anglicized to MacSheehan, Sheenan and Shean; while the prefix 'O' was added to early spellings as the inhabitants of Munster attempted to indicate their loyalty to the ancient Gaelic form of ieredom.
