Rincón is a barrio in the municipality of Cidra, Puerto Rico.

[3][4][5] Rincón 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 Rincón and Sur barrios was 901.

Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[13] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).

[14][15][16] The following sectors are in Rincón barrio:[17] Barriada I, Barriada II, Candelas, Chichón, Cotto, Entrada Capilla, García I, García II, La Herradura, La Línea, La Veguita, Los López, Nogueras, Rancho Díaz, Rafael Berríos, Torres, Villa Rosa, and Vitín La Torre.
