The High Tide Organ was a tidal organ 15 metres tall constructed in 2002 as part of "The Great Promenade Show" series of sculptures situated along Blackpool's New Promenade in the UK. It was removed in early 2022. The artwork, described as a "musical manifestation of the sea", is one of a few examples of a tidal organ; others include the San Francisco Wave Organ and the Sea Organ in Croatia.
