Tapantí National Park, sometimes called Orosí National Park, is a National Park in the Pacific La Amistad Conservation Area of Costa Rica located on the edge of the Talamanca Range, near Cartago. It protects forests to the north of Chirripó National Park, and also contains part of the Orosí River. The area known as Macizo de la Muerte was added to the park on January 14, 2000.

Three new species of Lepanthes orchids were discovered in the park in 2009 and is so far their only known habitat. All three species, L. graciosa, L. machogaffensis, and L. pelvis, are miniature orchids and neither is longer than 5 mm. They were discovered by a team from the Lankester Botanical Garden and the University of Costa Rica
