Rabo de Junco (also: Monte Leão) is a hill on the west coast of the island of Sal in Cape Verde.

It is situated at the northern end of the Baía da Murdeira, 8 kilometres (5.0 mi) southwest of the island capital Espargos.

Its steep eroded south face towards the bay is an important nesting area for birds.

Rabo de Junco and the surrounding 154 hectares (380 acres) are protected as a nature reserve.

[4] To its west lies the uninhabited islet Ilhéu Rabo de Junco.
