RFA Wave Ruler is a Wave-class fast fleet tanker of the Royal Fleet Auxiliary (RFA) of the United Kingdom tasked with providing fuel, food, fresh water, ammunition and other supplies to Royal Navy vessels around the world.

Wave Ruler was built by Kvaerner Govan (after 1999, BAE Systems Marine) and launched in 2001. She was accepted into service in 2003 and is the second ship to bear this name in RFA service. Wave Ruler and her sister Wave Knight, were designed to replace Olna and Olwen, two 36,000-ton Ol-class fast fleet tankers which were built at Swan Hunter and Hawthorn Leslie in the 1960s.[9]

Wave Ruler was the last tanker commissioned into the RFA until RFA Tidespring became operational in late 2017.
