Yauco (Spanish pronunciation: [ˈʝawko]) is a city (ciudad) and municipality in southwestern Puerto Rico, centered on the city of the same name. Although the city is inland, the municipality stretches to a southern coast facing the Caribbean. Yauco is south of Maricao, Lares and Adjuntas; east of Sabana Grande and Guánica; and west of Guayanilla. The municipality has 20 wards and the main city Yauco zona urbana (Yauco Urban Zone). It is both a principal city of the Yauco Metropolitan Statistical Area and the Ponce-Yauco-Coamo Combined Statistical Area.
It was founded by Fernando Pacheco on February 29, 1756, and developed for commodity crops of tobacco, sugar cane, and coffee. Yauco became a center for Corsican immigration to Puerto Rico in the 19th century due to its geographical similarity to their homeland. Corsicans have contributed to many areas of life in Yauco, particularly to its coffee industry. This has contributed to the city's nicknames of El Pueblo del Café (City of Coffee), and Los Corsos (The Corsicans). It is also known as La Capital Taína (the Taíno capital) after the native peoples of Puerto Rico.
