Osuna (Spanish pronunciation: [oˈsuna]) is a town and municipality in the province of Seville, southern Spain, in the autonomous community of Andalusia.

[2] Among famous people associated with Osuna is Juan de Ayala, the commander of the first European ship to enter the San Francisco Bay in California.

The origin of Osuna dates back to about three thousand years ago, when the Turdetans inhabited the city that would later be known as Urso.

C., fulfilling a previous forecast by Julius Caesar, it was refounded by Mark Antony with veterans of the last civil wars, giving it the status of a colony of Roman citizens and the official name of Colonia Genetiva Iulia, also documented in some inscriptions.

Its founding colonial law is preserved, although incomplete, an important bronze inscription on several tables, known as Lex Ursonensis[3] (although the name "Urso" does not appear on it even once), which is kept in the National Archaeological Museum of Madrid.

The vaults, which are supported by Moorish arches, contain the tombs of the Girón family, and the church was founded by Don Juan Téllez.
