"Rock Lobster" is a song written by Fred Schneider and Ricky Wilson, two members of The B-52's. It was produced in two versions, one by DB Records released in April 1978, and a longer version, which was part of the band's 1979 self-titled debut album, released by Warner Bros. The song became one of their signature tunes and it helped launch the band's success.

Spiny lobsters, also known as langouste or rock lobsters, are a family (Palinuridae) of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, South Africa, and the Bahamas, sometimes called crayfish, sea crayfish, or crawfish ("kreef" in South Africa), terms which elsewhere are reserved for freshwater crayfish.
