Garajonay National Park (Spanish: Parque nacional de Garajonay) is located in the center and north of the island of La Gomera, one of the Canary Islands (Spain). It was declared a national park in 1981 and a World Heritage Site by UNESCO in 1986. It occupies 40 km² (15 sq mi) and it extends into each of the municipalities on the island.

The park is named after the rock formation of Garajonay, the highest point on the island at 1,484 m (4,869 feet). It also includes a small plateau whose altitude is 790-1,400 m above sea level.

The park provides the best example of laurisilva, a humid subtropical forest that in the Tertiary covered almost all of Europe. It is also found on the Azores and the Madeira Islands. Laurus azorica, known as Azores Laurel, or by the Portuguese names Louro, Loureiro, Louro-da-terra, and Louro-de-cheiro, can be found in the park, as well as Laurus canariensis, known as Canary Laurel. Although named as a single type of forest, the National Park englobes several varieties of forests. Most humid and protected valleys oriented to the North have the richest and most complex forests. It is known as valley laurisilva, a true subtropical rainforest where the largest laurel trees can be found. At higher altitudes, with less protection from wind and sun, the forest loses some of its more delicate species. Here it is called slope laurisilva (laurisilva de ladera). At the south the forest is mainly a mix of beech and heather, species adapted to the less humid atmosphere.
