Aguilares is a census-designated place (CDP) in Webb County, Texas, United States.
It is named for the first settlers and ranchers, José, Locario, Francisco, Próspero, and Librado Aguilar.
It became a stop on the Texas-Mexican Railroad in 1881 and was granted a post office nine years later.
The population (thought to be a huge exaggeration) was given as 1,500 in 1910 – but four years later it was reportedly a mere 300.
The population rose to twenty-five by 1945, but the 1990 census again reported ten residents.
