HMS Leander (F109) was the nameship of the Leander-class frigate of the Royal Navy (RN). She was originally intended to be part of the Rothesay class and would have been known as Weymouth. Leander was, like the rest of the class, named after a figure of the classical Greek mythology. She was built by the Harland & Wolff shipyard in Belfast, Northern Ireland and was launched on 28 June 1961. She was commissioned on 27 March 1963.
