Repovesi National Park (Finnish: Repoveden kansallispuisto) is situated in the municipalities of Kouvola and Mäntyharju, only a few hours north-east of the more populous Helsinki area of southern Finland.

Formerly a site for intensive commercial forestry, the Repovesi area successfully transformed into a pristine national park.

Attractions include the Olhavanvuori hill, popular among climbers, and the Kultareitti water taxi route.

Also located in the park are the Kuutinlahti bay with its restored timber rafting channels, the Lapinsalmi suspension bridge, and many observation towers.

The common fauna of the park includes the red-throated diver, the Eurasian lynx, the moose, many owls and several galliformes.
