The Atlantic 85 is a third-generation B-class rigid inflatable boat (RIB) inshore lifeboat. It is operated around the shores of the British Isles and the Channel Islands by the Royal National Lifeboat Institution (RNLI). It was developed from the Atlantic 21 and the later Atlantic 75. It entered service in 2005, and gradually replaced the Atlantic 75.

The Atlantic design of the B-class of lifeboats is named after Atlantic College, where the design was developed.
