Ribeira Grande is a municipality on the island of Santo Antão of the Barlavento group in Cape Verde. It covers one-third of the island and is home to two-thirds of the population. It was founded in 1990 when the island broke up into three municipalities and ended island-wide administration from Porto Novo. Farmlands dominate the Atlantic Coastline and central valleys. Grasslands, bush, and forests cover the mountainous parts and the central part, along with dry lands. The taller mountains lie to the south. Its main economy are businesses in Ribeira Grande and tourism, followed by agriculture which is one of the main industries.
