Linnahall (Estonian: Tallinna Linnahall, 'Tallinn City Hall') (originally the V. I. Lenin Palace of Culture and Sports) is a multi-purpose venue in Tallinn, Estonia. It is situated in the harbour, just beyond the walls of the Old Town, and was completed in 1980. It is not to be confused with the primary administrative building of the historical municipal government (Raad) of Tallinn, often referred to as the Town Hall. The venue also features a heliport and a small sea port (formerly used by Copterline and Linda Line for connections to Helsinki).
