Morro de Areia Nature Reserve (Portuguese: Reserva Natural do Morro de Areia) is a nature reserve covering the southwestern coast of the island of Boa Vista in Cape Verde. It takes its name from the hill Morro de Areia, 167 m (548 ft) elevation. The natural reserve covers 21.31 km of land area, and stretches along the coast from the Praia de Chaves in the north to the Praia de Santa Monica in the south. The reserve includes a 300 m wide marine protection zone, an additional 4.36 km.

The nature reserve was established in order to protect the sand dynamics of the dunes, and endemic wildlife species including red-billed tropicbird, osprey, turtles, nurse shark, and numerous invertebrates.
