Bosco is an Irish children's television programme produced during the late 1970s and 1980s. It was produced and shown by RTÉ in Ireland. Designed by Jan Mitchell, Bosco was voiced by Jonathan Ryan initially, in the pilot series that was broadcast, with four presenters per show, in 1979. When the show went into full-time production in 1980, with two presenters per show, Miriam Lambert took over. From the 1981 season onwards, Paula Lambert took over. Bosco's name was chosen by Helen Quinn, sister of presenter Marian Richardson.
