South Horizons (Chinese: 海怡半島; Cantonese Yale: Hóiyì Bundóu) is an underground MTR rapid transit station in Hong Kong, located on Ap Lei Chau in Southern District. It is the southern terminus of the South Island line. The station is located under the junction of Yi Nam Road and South Horizon Drive, and primarily serves residents of the South Horizons private housing estate (its namesake), in addition to Ap Lei Chau Estate and Ap Lei Chau West Industrial Area. The station has a unique shape in the form of a letter Y, and has no overrun track. It opened on 28 December 2016 with the rest of the South Island line.

The station was built by the Leighton Asia – John Holland Joint Venture under a contract numbered 904, awarded May 2011, which also included Lei Tung station and sections of running tunnel. It was constructed using the cut-and-cover method.
