Kuala Selangor Nature Park, Protected coastal area in Kuala Selangor, Malaysia.

Kuala Selangor Nature Park is a protected coastal area containing three ecosystems: a brackish-water lake, mangrove forest, and secondary woodland. These habitats support a wide range of native wildlife and birds throughout the year.

Virgin mangrove forest stood at the site until the 1940s, but from 1965 to the 1970s the land was cleared for salt evaporation ponds. In 1986 clearing began again for a marina, prawn farm and golf course, and sand dredging destroyed much of the mangrove. The Malaysian Nature Society and the Asian Wetlands Bureau petitioned the Selangor state government, which established the park on 27 September 1987; it became the first park in Malaysia managed by an NGO.

The park's name in Malay, Taman Alam Kuala Selangor, is used on local signboards alongside the English one. Its 1.5 km Mangrove Walkway leads into stands of bakau kurap, buta-buta and perepat, three of the 13 mangrove species recorded there. Groups of more than 20 can book sessions such as mangrove tree planting and night walks.

Three main walking paths guide visitors through the area: the Bund Trail circles the lake, the Main Trail winds through forest, and the Mangrove Walkway crosses wetland areas. Early morning or late afternoon visits offer the best chances to spot wildlife.

The park's logo is the endangered silvered-leaf monkey, adopted when the reserve was created. An abandoned aviary still stands in the middle of the park, a remnant of the milky stork breeding programme that was suspended.
