Jingyuetan National Forest Park, National forest park in Changchun, China.

Jingyuetan National Forest Park is a forest park near Changchun that spans across a substantial area combining a central lake with surrounding woodlands. The grounds feature multiple vantage points and pathways for visitors to explore the landscape.

The park began in the 1930s as a water supply project for Changchun and expanded over the following decades. It grew from its original size into a larger protected area by the early 2000s.

Beiputuo Temple sits within the park grounds as a Buddhist place of worship that emerged in the 1990s and draws visitors seeking spiritual spaces. The temple reflects how faith and nature coexist in this region of China.

The park maintains walking paths and offers bus rides for visitors who prefer not to walk the entire area. Comfortable footwear and seasonal clothing are recommended since weather and ground conditions change throughout the year.

The lake's crescent outline gave the park its name, "Clean Moon Lake". The reservoir was built between 1934 and 1936 to supply Changchun with water, holding 25.8 million tonnes behind a dam that cost 3.5 million yen. Two Jin dynasty tombs inside the park are listed as Changchun protected sites.
