Radio Lollipop is a charitable organization providing a care, comfort, play and entertainment service for children in hospital.

Following the success of the first station, the International Year of the Child Committee provided funding in 1980 to develop Radio Lollipops in other British hospitals.

In most hospitals, the programme is wired to speakers in wards, rather than actually broadcast, but a central studio, with on-air presenters, provides a focal point and base, and is open to children.

Radio Lollipop is run entirely by unpaid volunteers, usually a mix of city business people, retirees and medical students, and usually operates in the evenings.

In 1985, the first Radio Lollipop outside the UK was started at the Princess Margaret Hospital for Children in Perth, Western Australia.
