The Desert de les Palmes Nature Reserve (Spanish: Parque Natural del Desierto de Las Palmas, Valencian: Desert de les Palmes) is a nature preserve in the province of Castellón, in the Valencian Community, Spain.

The 3,293 hectare area was declared a nature preserve by the valencian government on October 16, 1989.

The name of the preserve comes from the historical presence of a religious order of Carmelita Mendicants.

This order calls spaces that are dedicated to spiritual retreat "holy deserts" (los "Santos Desiertos"[1]).

The second part of the name comes from the abundance of palms (Chamaerops humilis) in the area.
