San Antonio is a barrio located in Caguas, a municipality in the north-central interior of Puerto Rico situated between the northern coastal plains and the eastern mountain ranges. The barrio covers approximately 4.32 square kilometers and forms part of Caguas's diverse neighborhoods, which span from urban commercial zones to more suburban and rural areas depending on proximity to the municipal center and major transportation corridors.

The landscape in this region of Caguas is characterized by the transitional geography typical of central Puerto Rico—a mix of developed residential areas interspersed with agricultural land and natural vegetation. The terrain reflects the municipality's position between the coastal lowlands to the north and the interior highlands, creating a moderate elevation with tropical climate conditions consistent with the island's interior regions. Properties in San Antonio reflect this mixed-use character, with a combination of smaller residential parcels, some agricultural holdings, and areas of continuing suburban development.

Property ownership patterns in San Antonio are typical of established Puerto Rico barrios, with a mix of long-standing family residences and parcels held by investors and outside owners. The barrio's position within Caguas—itself a significant municipal hub with commercial and industrial activity—means that land use here balances residential livability with proximity to economic activity. Lot sizes vary across the barrio, ranging from compact urban-style parcels suited to modest single-family homes to larger tracts that may retain agricultural uses or allow for expanded development potential.
