[3][4][5] Tetuán was in Spain's gazetteers[6] until 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 an unincorporated territory of the United States.

In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Tetuán barrio was 1,678.

On May 28, 2019 a landslide occurred in Tetuán cutting off many families' access to the main road, Puerto Rico Highway 140.

The mayor said landslides are a normal occurrence in the Utuado municipality.
