St Stephen's College (Chinese:聖士提反書院) is a Christian Direct Subsidy Scheme co-educational secondary school in Stanley, Hong Kong.

A group of prominent Chinese businessmen approached the Church Missionary Society to administer a school for their sons.

In the 1920s, the government granted the school 37 acres (150,000 m2) on the Stanley Peninsula in recognition of outstanding contributions to education.

The foundation stone was laid in April 1928 by the Governor of Hong Kong, Sir Cecil Clementi, and in May 1929, the college was fully functional in its new buildings, many of which are still in use today.

During the Battle of Hong Kong in the Second World War, heavy fighting took place around the college, which was among the last British strongholds to surrender to the Imperial Japanese Army.

The IBDP is a two-year curriculum and is monitored under the International Baccalaureate Organization rather than the Education Bureau of Hong Kong.

St. Stephen's College Preparatory School was founded in 1938 with only one building for classrooms, boarding house and dining hall.
