S. Thomas' College, Bandarawela is a selective entry boys' private school, situated in the town of Bandarawela in the Uva Province, Sri Lanka. It is an Anglican school administrated by the Church of Ceylon.

The college is run by a Board of Governors which is chaired by the Anglican Bishop of Colombo, who is also known as the Visitor of the College. The administration of the college in itself is headed by a headmaster who is an Anglican priest. Admission to the college is at the sole discretion of the headmaster.

S. Thomas' Preparatory School in Bandarawela was founded by W. T. Keble on 20 January 1942. Keble had originally conceived the idea of establishing an upcountry school as early as 1929, following a visit to Nuwara Eliya. However, he ultimately selected Bandarawela as the ideal location, owing to its favourable climate.

In 1957, V. D. Paul Raj assumed the role of headmaster and oversaw the completion of the chapel of the Good Shepherd in 1960. Under successive leadership, the college attained junior secondary school status in 1969 and later progressing to senior secondary school status in 1975. In 1981, it was renamed S. Thomas’ Collegiate School, and in 1989 was renamed to S. Thomas’ College.

The most recent headmaster is P. H. Navarathna, who was appointed in 2023.

This annual cricket encounter between S. Thomas' College, Bandarawela and S. Thomas' College, Gurutalawa, both being part of the Thomian family, was started in 1984. The fixture was abandoned in 1987 due to a number of reasons. The fixture was resumed after the idea was mooted by the OBA of STC Bandarawela supported by the OBA of STC Gurutalawa and the two Headmasters agreed to continue the ‘Uva Thomian Cricket Encounter’ (UTCE) on a grand scale in 2009. The match is played for a trophy to commemorate the two headmasters of Bandarawela and Gurutalawa who were responsible for starting the fixture; S. L. A. Ratnayake and Patrick Gunawardene.

This annual inter-school W. T. Keble Memorial Soccer Tournament takes place between S. Thomas' College, Bandarawela and S. Thomas' Preparatory School, Kollupitiya, both being part of the Thomian family.
