Radio London, also known as Big L and Wonderful Radio London, was a top 40 (in London's case, the "Fab 40") offshore commercial station that operated from 23 December 1964 to 14 August 1967, from a ship anchored in the North Sea, three and a half miles (5.6 km) off Frinton-on-Sea, Essex, England.

The station, like other offshore radio operators, was dubbed a pirate radio station, and went off air following the introduction of the Marine, &c., Broadcasting (Offences) Act 1967 which made it illegal to supply or assist such stations except in an emergency. The station was notable for helping to launch the careers of various disc jockeys who went on to work at BBC Radio 1. Its offices were in the West End of London at 17 Curzon Street, just off Park Lane.
