Villalba (Spanish pronunciation: [biˈʎalβa]), originally known as Villa Alba, is a town and municipality of Puerto Rico located in the central region, northeast of Juana Díaz; south of Orocovis; and west of Coamo.

[2] Hurricane Maria passed through the area on September 20, 2017 and triggered numerous landslides in Villalba with significant rainfall.

The mountainous geography of Villalba made restoring electricity and water services extremely challenging.

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

[21][22] An Energy Consortium was signed in late February, 2019 by the mayors of Villalba, Orocovis, Morovis, Ciales and Barranquitas municipalities.

It is intended to have municipalities work together to safeguard their communities, in the event of a catastrophe, by creating resilient, and efficient energy networks with backups.

del Carmen is a religious and cultural celebration that generally features parades, games, artisans, amusement rides, regional food, and live entertainment.

The city belongs to the Puerto Rico Senatorial district VI, which is represented by two Senators.

In 2024, Rafael Santos Ortiz and Wilmer Reyes Berríos were elected as District Senators.

By 1927, Villalba was connected to Juana Díaz, and other neighboring municipalities with Puerto Rico Highway 149.
