The Baca Chica is a threatened strain of the Spanish Mustang, which originated in New Mexico. It is named after the Baca family, most notably Joty Baca, who preserved this strain.

The Baca farm was established in New Mexico in the 19th century. A century later, a family member called Doroteo "Joty" Baca realized that the Baca horses where pure descendants of the Spanish horses who were brought to the Americas during the Spanish colonization, and decided to dedicate his life to the preservation of the Baca strain. Together with his wife Virginia, Joty carefully bred the Baca horses to maintain their purity and qualities, and acted to increase public awareness of this strain. In 2013 Joty passed away, but the efforts to preserve the Baca Chica strain continue to this day.

Baca Chica horses are known for their intelligence and endurance, two qualities for which they were bred. They come mostly in the solid colors of chestnut, bay, black, or grey, but spotted horses with varnish roan or white blanket patterns also occur. Baca Chica horses usually stand between 14.1hh and 14.3hh, though shorter and taller individuals can be found.
