The Guerrero Correctional Institution (Institución Correccional Guerrero) is a prison for men located in Aguadilla, Puerto Rico, owned and operated by the Puerto Rico Department of Corrections and Rehabilitation.

[1] The facility was first opened in 1986 as a Community Therapy mental health unit (Comunidad Terapéutica de Guerrero) of the Puerto Rico Department of Health.

As of 2008 about a third of its inmates were pre-trial detainees, and the others were serving longer sentences at minimum security.

[2] From 2002 to 2008, some 53 Guerrero inmates died inside the institution, all but one of them pre-trial detainees, and 73% of them within their first week behind bars, most of them homeless.

An extensive report by the ACLU of Puerto Rico blamed the abuse of a horse tranquilizer, Xylazine, among inmates, and lack of appropriate medical attention and lack of accountability among prison officials.
