Trujillo Alto (Spanish pronunciation: [tɾuˈxiʝo ˈalto]) is a town and municipality of Puerto Rico. Located on the northeastern coastal plain on the boundary between the Northern Karst Belt and Sierra de Luquillo, it is north of Caguas and Gurabo, southeast of San Juan, and west of Carolina. Its geography features river lowlands and mountains. Part of the San Juan metropolitan area, Trujillo Alto is spread over 6 barrios and the downtown area and administrative center of Trujillo Alto Pueblo.

Trujillo Alto was officially founded in 1801, but gained more importance during the 20th century. Due to its proximity to the capital, San Juan, the city has become a suburb of the metropolitan area, which has sparked its growth during recent years. The population of Trujillo Alto has increased through the last century from 9,576 (1930) to 74,482 (2010). According to the 2010 Census, it is Puerto Rico's tenth-most populated municipality. The urban setting of Trujillo Alto is compact, being divided into the barrios Carraízo, Cuevas, Dos Bocas, La Gloria, Quebrada Grande, Quebrada Negrito, Saint Just and Pueblo.

In 1953–54, the Carraízo hydroelectric dam was constructed in Trujillo Alto by the Sumner Sollitt Construction Company of Chicago, under contract by the Puerto Rico Water Resources Authority. The dam forms the Loíza Lake, a reservoir which serves as the main source of the water supply for San Juan, Puerto Rico.
