Tin Hau does not refer to a formal district but to an area so called by some people in Hong Kong. To be more formal in indicating areas of Causeway Bay which is near to the Tin Hau Station of the MTR, Causeway Bay (Tin Hau) is used. Most definitions of Tin Hau include areas in southeastern Causeway Bay, Hong Kong surrounding the MTR Tin Hau Station, so named due to its proximity to the Causeway Bay Tin Hau Temple.
The term "Tin Hau" is also used to describe the location of places like Queen's College (just beside Tin Hau MTR Station) and the Central Library (Tin Hau station B exit's name) and the Causeway Bay Sports Ground which is located in the Wan Chai District. Several government offices and facilities such as Causeway Bay Market are located there.
