Sizihwan (Chinese: 西子灣; Hanyu Pinyin: Xīzǐwān; Tongyong Pinyin: Sizǐhwan) is a community and sightseeing spot in Gushan District, Kaohsiung, Taiwan, named for the adjacent bay of the Taiwan Strait, also called Sizihwan.

[1] The name Sizih (西子) can also refer to Xi Shi, an alternative name used by the poet Su Dongpo of the Song dynasty referring to the famous ancient beauty, which somehow implies the view in this scenic area is as beautiful as the lady.

Historical names include: Located on the Taiwan Strait at the north of the entrance to Kaohsiung Harbor, Sizihwan is surrounded by mountains with Shoushan to the northeast and Shaochuantou Hill (哨船頭山), a spur of Shoushan to the east.

The area is dominated by the campus of National Sun Yat-sen University which faces the open waters of the Taiwan Strait.

The Former British Consulate at Takao and the historic Lingsing Temple [zh] at the peak of Shaochuantou overlook Sizihwan Bay.
