Live at the Marquee is a season of music concerts and other live performance events organised by Aiken Promotions in a large marquee in Cork, Ireland, every summer since 2005. For about a month in June and July, a concert is held most evenings; tickets for each night are sold separately, with varying lineups and pricing. Acts have represented many genres of popular music, including rock, folk, electronic, hip hop, rhythm and blues, and country; as well as stand-up comedy acts.
