'Sir Henry's' was a bar and nightclub on South Main Street in Cork, Ireland, which opened in 1978 and closed in June 2003 with the building subsequently being demolished. The name is derived from Henry O'Shea who was a baker and building proprietor in the South Main street area of Cork city. The club was renowned for its Dance, Trance, R&B, Hip Hop and a regular live rock.

Sir Henrys was ostensibly a rock bar for many of its early years. A large video screen in front of the stage showed rock videos for customers. It also served food for a period of time from its small kitchen before this was closed in favour of additional bar space and cloakroom facilities.

Many of Ireland's up and coming young bands performed here and the 'Battle of the Bands' was held there for many years where uinsigned talent competed for a lucrative recording contract. Many famous artists performed there over these years including the late Phil Lynott, John Martyn's folk-inspired electric and acoustic sets, ex-Clash Mick Jones' Big Audio Dynamite and The Pogues.
