Jagüey is a barrio (county) in the municipality of Aguada, Puerto Rico.

[3][4][5] It is located west of the center of Aguada partly bordering the municipality of Rincón.

Jagüey 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 combined population of Jagüey and Atalaya barrio was 1,195.

Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[14] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).
