The Paluma-class motor launch was a class of four hydrographic survey motor launches operated by the Royal Australian Navy (RAN). Built in Port Adelaide between 1988 and 1990, the four catamarans were primarily based at HMAS Cairns in Cairns, Queensland, and operated in pairs to survey the waters of northern Australia.
