Lok Fu (Chinese:樂富) is a place in Wong Tai Sin District, Kowloon, Hong Kong. It is located at the east of Kowloon Tsai, the west of Wong Tai Sin and the north of Kowloon City. It geographically includes nearby Wang Tau Hom.

It was named as Lo Fu Ngam (Chinese:老虎岩, literally "Tiger's Den" in Chinese). After the construction of public housing estate was started in 1957 with the first resettlement blocks being built, Lo Fu Ngam was renamed as Lok Fu which literally means "Happiness and Wealth" in Chinese.
