St. Hilda's Secondary School (SHSS) is a co-educational government-aided Anglican secondary school in Tampines, Singapore, which offers a four to five-year course leading to a GCE 'O' Level and/or a GCE 'N' Level.

Named after the saint Hilda of Whitby, it is affiliated with the Anglican Diocese of Singapore and St. Andrew's Junior College.

St. Hilda's traces its origins to a small private school, Bethel English School, founded in 1929 in a small two-storey building at Ceylon Road.

During the Japanese occupation, the school came under Japanese control but continued functioning, unlike many other mission schools which were either closed down or destroyed.

The post-war years were a period of rapid development as the school grew and expanded.
