Tapantí – Cerro de la Muerte Massif National Park, also known as Parque Nacional Tapantí – Macizo Cerro de la Muerte in Spanish, is a national park in Costa Rica's Central Conservation Area. It is located near the edge of the Talamanca Range, close to Cartago. The park helps protect forests north of Chirripó National Park and includes part of the Orosí River. The area called Cerro de la Muerte Massif was added to the park on January 14, 2000.

The southwest border of the protected area is partly along Route 2, also called the South Inter-American Highway. To the other side of this road are Los Quetzales National Park and Los Santos Forest Reserve.

Ecology

The park spans 583.20 square kilometers (225.17 square miles) and includes two types of ecosystems: lower mountain rainforest and pre-mountain rainforest. These forests are home to about 45 mammal species, such as the Baird's tapir, kinkajou, white-faced capuchin monkey, paca, agouti, ocelot, and jaguarundi. The park is also home to 400 bird species, including sparrow hawks, resplendent quetzals, emerald toucanets, and violaceous trogons. There are 28 species of reptiles and amphibians, and a large number of insects, including the Thysania agrippina, which is the largest moth in the American continent.

In 2009, scientists discovered three new species of Lepanthes orchids in the park. These orchids are only found in this area and are the smallest of their kind, with none growing longer than 5 mm. The species are named L. graciosa, L. machogaffensis, and L. pelvis. They were identified by a team from the Lankester Botanical Garden and the University of Costa Rica.

A portion of the Turberas de Talamanca Ramsar site is located within this protected area. This area is shared with Chirripó National Park, Los Quetzales National Park, Macho River Forest Reserve, Vueltas Hill Biological Reserve, and Los Santos Forest Reserve.
