Peñuelas (Spanish pronunciation: [peˈɲwelas], locally [peˈɲwelaʔ]) is a town and municipality in Puerto Rico located in the Peñuelas Valley on the southern coast of the island, south of Adjuntas, east of Guayanilla, west of Ponce and north of the Caribbean Sea.

Later gradually retreated deeper into the valley, heading tobarrios the most fertile land which would then be part of the town of Peñuelas.

[4] Nationalists Melitón Muñiz Santos, Roberto Jaume Rodríguez, Estanislao Lugo Santiago, Marcelino Turell, William Gutiérrez and Marcelino Berríos were arrested and accused of participating in an ambush against the local insular police.

The municipal buildings, central square and large Catholic church are located in a barrio referred to as "el pueblo".

[19] Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became a territory of the United States.

In the center it has a purple or violet cross: symbol of Christianity and its ecclesiastical order; it represents the spiritual life.

The cross represents Santo Cristo de la Salud that "stopped the sea from flooding Peñuelas".

The blue and white symbolize the choppy sea and the regal ensign represents the faith in Christianity, "In God We Trust".

The Fiestas Patronales de San Jose is a religious and cultural celebration that generally features parades, games, artisans, amusement rides, regional food, and live entertainment.

The origin of this name dates back to the days when Peñuelas was home to a major petro-chemical complex known as CORCO.

Peñuelas' public bus service ("la guagua") connects passengers to Ponce city (east) and Guayanilla (west).
