The Arun-class lifeboat was a fast all-weather lifeboat designed by the Royal National Lifeboat Institution (RNLI) for service at its stations around the coasts of the United Kingdom and Ireland. They were operated by the RNLI between 1971 and 2008. Many have been sold to see further service in the lifeboat and coastguard services of other countries.

The class takes its name from the River Arun in Sussex, England.
