Luagan Lalak Forest Recreation Park (Malay: Taman Rekreasi Hutan Luagan Lalak) is a protected recreational forest in Mukim Labi, Belait District, Brunei. It is a significant wetland conservation area under the jurisdiction of the Forestry Department, valued for its role in biodiversity protection and ecological importance. Unlike many recreational forest parks that include disturbed or plantation forests, Luagan Lalak remains a natural wetland ecosystem, underscoring its significance in conservation efforts.

The park is situated nearly 100 kilometres (62 mi) from Bandar Seri Begawan. Visitors travelling from the capital can reach Kampong Sungai Liang in about an hour via the Telisai–Lumut Highway, where a left-hand exit leads to Jalan Labi. From there, the park is an additional 25 kilometres away. As public transportation does not serve the area, access to the park requires private vehicle transportation.

The park's name is derived from the Brunei Malay word luagan, which means a large non-flowing water body, while lalak is believed to be an error in either the spelling or pronunciation of the word dalak (Channa striata), a snakehead fish common in Brunei waters.

Yahya Bakar, who was the minister of industry and primary resources at the time, initiated the groundwork in 1993. Initially, only 10 hectares were opened to the public, with the park undergoing further repairs before its official reopening in 2012 to commemorate World Forestry Day. By May 2018, Luagan Lalak had welcomed over 81,000 visitors since 2001.

Situated within the Labi Hills forest reserve, Luagan Lalak is a 270-hectare (670-acre) alluvial freshwater swamp (empran), notable for its dark waters and expansive fields of Lepironia articulata (purun)—grass-like plants with triangular stems and small blossoms. This unique ecosystem supports a diverse array of insects, birds, and small fish. A 200-metre (660 ft) wooden bridge spans the swamp's waters. The park's amenities consisted of three gazebos, walkways, benches, and a barbecue pit. Restroom facilities are located across the road from the forest reserve's entrance.

Numerous elusive terrestrial mammals, such as the Sunda pangolin, maroon leaf monkey, colugo, and Horsfield's tarsier, can be found in Luagan Lalak. Because of the abundance of birds, photographers and birdwatchers come to see both migratory and local species. Among the notable birds are the garnet pitta, argus pheasant, Storm's stork, Bornean bristlehead, rhinoceros hornbill, great slaty woodpecker, crested fireback, red-billed malkoha, common kingfisher, buffy fish owl, yellow-rumped flowerpecker, black-and-yellow, black-and-red, and green broadbill.
