The Kuala Langat North Forest Reserve (KLNFR) is a 957.6 ha protected peat swamp forest in the Kuala Langat District of Selangor, Malaysia. Some forests within the reserve are 8,000 years old. The reserve is used by some members of the indigenous Temuan people.
First gazetted in 1927 with an area of 7,246.96 ha, the reserve has shrunk since then, with land around it developed into housing and agricultural areas. Proposals to degazette the majority of the park occurred in 2020 and 2021, and much of the park was degazetted in 2021. However this action was reversed amid widespread opposition.
