The 52-hertz is an individual whale of unidentified species, which calls at the unusual frequency of 52 Hz.

This pitch is a much higher frequency than that of the other whale species with migration patterns most closely resembling this whale's – the blue whale (10–39 Hz) or fin whale (20 Hz). It has been detected regularly in many locations since the late 1980s and appears to be the only individual emitting a whale call at this frequency. 52Hz has been described as the "world's loneliest whale."
