The Kouchibouguac National Park (English Kouchibouguac National Park of Canada, French Parc national du Canada Kouchibouguac ) is a Canadian National Park in New Brunswick ( eastern Canada ) north of Richibucto.

It has an area of 238 km ² and was founded in 1969. The park consists of sandbanks, dunes (length: 25 km ), lagoons, salt marshes, and forests. It provides a habitat for seabirds, such as the endangered Yellow-footed plover. Here is the second largest Seeschwalbenpopulation North America. In the Everglades National Park, among others thrive Pitcher plants. Butterflies, such as Limenitis archippus (English: Viceroy Butterfly ) can be observed here also.

The name is derived from the name of the river Kouchibouguac River, which flows through the park, in the language of the Mi'kmaq, an Indian tribe living in eastern North America. Other rivers of the park are Black River and St. Louis River.

The site is designated in its entirety as a Dark Sky Preserve ( light protected area, Kouchibouguac Dark Sky Preserve ) 2009.
