Presidio de San Bernardino, Arizona was a Spanish fortress founded in 1776 that was located about 18 miles east of present-day Douglas, Arizona.
It was established by Irish mercenary Hugh O’Conor, as part of a network of presidios and missions in present-day southern Arizona. The other missions were:
However, these forts were under constant attack from hostile Apache Indians and were unable to adequately protect themselves, much less build and protect any surrounding missions. Presidio de San Bernardino was abandoned just four years later in 1780.

The Presidio was also known as Presidio de San Bernardino de Terrenate, Fort San Bernardino and Camp San Bernardino Springs.
