Cornwall Street Park, Urban park in Sham Shui Po District, Hong Kong.

Cornwall Street Park is an urban green space with walking paths, benches for resting, and play areas for children. The space sits between residential buildings and offers different zones for various types of visitors.

The park opened in 1995 on the site of Siu Sai Wu village, which was demolished in 1981–1982 to build Kowloon Tong railway station. It is managed by the Leisure and Cultural Services Department. In 2012 it was fully renovated under the theme "City Flow", with new signage, remodelled facilities and three creative furniture pieces.

The park serves as a gathering space where neighbors exercise in the morning and spend time together. These daily interactions show how important such places are to community life in this densely populated area.

The park is easy to reach by public transportation and within walking distance of homes and shopping areas. The flat paths and open layout make it accessible for all visitors.

The park's water features are fed by a stream flowing down from Siu Sai Wu, the reservoir managed by the Water Supplies Department just above it. The site was formerly Siu Sai Wu village, cleared in 1981–1982 to build Kowloon Tong station.
