Marojejy National Park () is a national park in the Sava Region of northeastern Madagascar. It covers and is centered on the Marojejy Massif, a mountain chain that rises to an elevation of . Access to the area around the massif was restricted to research scientists when the site was set aside as a strict nature reserve in 1952. In 1998, it was opened to the public when it was converted into a national park. It became part of the World Heritage Site known as the Rainforests of the Atsinanana in 2007. Despite its rugged terrain, poaching and selective logging are still persistent problems, particularly since the start of the 2009 political crisis in Madagascar. Mining, slash-and-burn agriculture, and wood collection also pose threats to the park and its wildlife.
