"The Lighthouse Polka" is an Irish polka in D Major. The parts are played AABB'. Accordion player Johnny O'Leary (1923-2004) of the Sliabh Luachra region of the Cork-Kerry border identified the tune as learned from fiddler Jack Connell, "the man of The Lighthouse. He's the man above at The Lighthouse in Ballydesmond". The Lighthouse was both the name of a pub and the name of the townland where Connell lived. The tune was unnamed ("Jack must have thousands of them"), so O'Leary suggested naming it "The Lighthouse". It was printed in Moylan's Johnny O'Leary (1994). It was recorded by Johnny O'Leary (1984).
