Salesian School is a split-site Roman Catholic comprehensive secondary school in Chertsey, Surrey. The two sites were originally a pair of single-sex education Roman Catholic private schools maintained by the Salesian Fathers and Sisters. The Salesian College at Highfield Road (previously Salesian Sixth Form), founded in 1919, was for boys and the later Guildford Road school was for girls. In 1971 they merged to form one comprehensive school but still maintained single-sex education on separate sites.

In 1981 it became a coeducational school with pupils located on sites according to their age or subject taught. As of 2009, however, years 7 to 11 (aged 11–16 years) began to exclusively study at the larger Guildford Road, while the college (ages 16–18) remains at Highfield Road – the students currently following a two-week timetable.
