San José de Ocoa is a Dominican province; it is on the southern side of the Cordillera Central ("Central mountain range"). Its capital has the same name, San José de Ocoa.

It was created on 6 September 2000 but it started on 1 January 2001. It was a municipality of the Peravia province before being raised to the category of province.

Name
The province is named after its capital city, San José de Ocoa. Ocoa is the name of the river that crosses the province; it is a Taíno word that means "a place with many mountains".

History
Bartolomé de Las Casas was the first person that wrote about the region when he said that Maniey (now, Maniel) was a Taíno province. Maniey or Maniel meant "a place where there are peanuts"; mani ( (Spanish) is the Taíno word for peanut. Peter Martyr d'Anghiera did not write about the Maniey but he wrote about a lake in the region of Rancho Arriba; there is not a lake (or lakes) there anymore, only a swamp.

For a long time, the region was visited only by monteros (men that hunted wild cows and pigs). Then some maroons (runaway slaves) came to live here, in the high mountains of the region. One settlement was called Maniel; since then, Maniel meant in Hispaniola a place where maroons live and not only the name of the region. 

The first settlement by maroons in the region is from the beginning of the 16th century and was called Maniel Viejo de Ocoa. This settlement lasted until 1666 or 1667 because many people died from smallpox and measles that affected the island in those years. There was also a military action in the region to capture maroons.

The second settlement was during the first years of the 19th century (around 1802), and it is known as Maniel de los Lorenzos ("Lorenzos' Maniel") because of the last name ("Lorenzo") of its founders. It was founded at El Canal, north of the city of San José de Ocoa.

Very soon some families from Baní, on the south, began to move to the region and made their houses at what is now the city of San José de Ocoa.

During the Dominican War of Independence (1844), there were two important battles in the region: the battles of El Memiso and of El Pinar, won by Dominican soldiers. So the Haitian soldiers could not go on to Santo Domingo, and had to go back to Haiti.

In December 1858, San José de Ocoa was made a municipality of the old province of Santo Domingo; in 1895, it was changed to a municipality of the Azua province. With the creation of the Peravia, San José de Ocoa was a municipality of that new province. Then, on 6 September 2000, San José de Ocoa was made a new province with the northern half of the Peravia province and with the municipalities of San José de Ocoa, Rancho Arriba and Sabana Larga, and the municipal district of La Ciénaga.

In 2004, Nizao-Las Auyamas and El Pinar became municipal districts, and El Naranjal in 2006.
