HMS Llandaff (F61) was a Salisbury-class or Type 61 aircraft direction frigate of the British Royal Navy, named for the district of Llandaff in Cardiff, Wales. She was built by Hawthorn Leslie and Company at Hebburn on the River Tyne, being laid down on 27 August 1953 and launched on 30 November 1955. Llandaff broke away from her moorings in a storm on 1 March 1956 and was damaged by collisions with the cruiser HMS Bermuda, the frigate HMS Russell and a merchant ship before she could be brought under control. Despite this damage, she completed on 11 April 1958, when she was the first ship to be trained by the newly established Flag Officer Sea Training organisation at Portland.
