Kai Yuen Street (Chinese: 繼園街) is a street in North Point, Hong Kong, that goes up Kai Yuen Hill. It is a historically rich street, once serving as the main access road to Kai Yuen, the influential Chan Wai Chow (陳維周) family's mansion. Kai Yuen was demolished in the late 1970s.

Currently it is mainly a residential area with high rise apartments such as Bedford Gardens on the west side, and 5–7-storey Mid-Century apartments on the east side.

The surrounding area was named after the mansion 'Kai Yuen', a Chinese Renaissance-style mansion constructed in 1938 and one of the largest of its kind in Hong Kong. It was once the residence of the Chan Wai Chow (陳維周) family, a family of warlords originating from Guangdong. Chan Wai Chow's brother was Chan Kai Tong, the famous general and governor of Guangdong.

After settling in Kai Yuen, Chan Wai Chow started to establish businesses such as hotels and cinemas in Hong Kong. Some of Chan Wai Chow's soldiers also settled in the area and established a variety of small shops and businesses.

After the end of the Japanese occupation of Hong Kong in World War II, North Point saw a boom in immigrants from Shanghai, Fujian, and the Philippines, causing a large demand for new buildings to be built. The period of the 1950s to the 1970s saw a variety of new developments in the Kai Yuen area, such as the construction of Chun Chu Temple, a Buddhist and Taoist temple founded in 1955 by a community of Hakka and Hainan people in North Point, as well as a batch of tenement buildings for residential and commercial purposes designed by Yum Koon Seng (Chinese: 任冠生), a prominent architect most known for designing luxury apartments at the time.

During the late 1970s, the last owners of Kai Yuen sold the mansion to developers, who promptly demolished it to redevelop the land into a private housing estate. Kai Yuen was replaced by Bedford Gardens in 1981, a large residential development with 12 building blocks.

Subsequently, tong laus (tenement housing) in Kai Yuen upper and Lower lane, as well as Kai Yuen Street No. 60–74 were demolished in 2011 and 2021 respectively. To be developed into high rise residential apartments.

Kai Yuen Terrace (Chinese: 繼園臺) is a short, sloped road that starts from the northern end of Kai Yuen Street. It is the main access route to private housing estates including Full Wealth Gardens, Kings Way Mansion, and Harbour Court.

Kai Yuen Terrace used to be the access road to the North Point branch of Yan Pak English Secondary School (仁伯英文書院). The school was founded by Seaker S.K. Chan (陳樹渠), the son of Chan Wai Chow.

Kai Yuen Upper, and Lower Lane was two streets connecting Kai Yuen Street that had rows of tong lau (tenement housing), including Kai Yuen Lau (繼園樓) and Fu On Lau (福安樓) built during the late 1950s. Both lanes were purchased by Stewart Leung Chi-kin (梁志堅) of New World China Land in 2010, and demolished in 2010–2011 for redevelopment. Currently, Fleur Pavilla stands on the original site.

The author and scholar Sima Cheung Fung (司馬長風) once lived in Kai Yuen Upper Lane during the 1970s.
