Sai Wan (Chinese: 西環), also known as Western district, or simply Western, is an area in Hong Kong Island, Hong Kong that corresponds to Sai Ying Pun, Shek Tong Tsui, Belcher Bay and Kennedy Town.

After Hong Kong's handover to People's Republic of China, Sai Wan become the location for the Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region and people in Hong Kong, including the former head of the Liaison Office Zhang Xiaoming,[3] colloquially refer the name Sai Wan as a metonym for the Liaison office itself.

In 1890s, a severe epidemic outbreak of the bubonic plague afflicted Sai Ying Pun residents.

The stone pond was located at modern-day Hill Road and The Belcher's, and was mined by the Hakka people since the 17th century.

In the meantime, the largest brothels in the city, which were located at the Possession Street, were destroyed by a big fire.

Brothels in this area had also inspired numerous novels and Hong Kong films, most notably Rouge (1987), starring Anita Mui and Leslie Cheung.

It was named after the governor Arthur Edward Kennedy who initiated land reclamation along the coast of this area in 1886.

From 1933 to 1939, more land was reclaimed along the coast of Kennedy Town, yet the construction was suspended due to the Battle of Hong Kong in 1941.
