Blue and John Crow Mountains National Park is a national park located in Jamaica. The park covers an area of 495.2 square kilometers and makes up 4.5% of Jamaica's total land area. It is named after the Blue Mountains, a mountain range that runs through the park, and the "John crow," a bird commonly found there known as the turkey vulture (Cathartes aura). The park is known worldwide for its rich variety of plant and animal life. It is one of only two places where the giant swallowtail butterfly (Papilio homerus), the largest butterfly in the Western Hemisphere, lives. The park also provides a home for the endangered Jamaican blackbird (Nesopsar nigerrimus), the Jamaican boa (Chilabothrus subflavus), and the Jamaican hutia (Geocapromys brownii).

The park was added to the list of UNESCO World Heritage Sites on July 3, 2015, for both cultural and natural reasons.
