Pirate Radio Four was a magazine show broadcast on BBC Radio 4 in 1985-6. Part of the station's drive to attract younger listeners, it was broadcast during the mornings in the school summer holidays and was aimed at children of about 8–14 years old. It also had a sister programme, Cat's Whiskers, aimed at younger listeners.
The show was particularly noted for featuring a new Doctor Who serial, Slipback, during its first run, and also featured regular appearances by Sue Townsend's character Adrian Mole. The host was Steve Blacknell.
