Cazalilla is a village in the province of Jaén, in the Andalusia region of southern Spain. It is one of the many small municipalities that make up the Jaén countryside, a province known for its olive-growing landscapes in the Guadalquivir valley and surrounding hills.
According to 2024 figures from Spain's National Statistics Institute (INE), Cazalilla had a population of 771 inhabitants. That number places it among the smaller settlements of the province, typical of the rural villages that dot this part of Andalusia.
As a village of fewer than a thousand residents, Cazalilla is defined chiefly by its small scale and its location within Jaén, rather than by any large urban features. Its administrative status is that of a municipality within the province of Jaén.
