Archaeological excavations at the castle of Lorca (Murcia, Spain) led to the identification of part of the Jewish district of the town. This area, occupied between the 14th and 15th centuries, represents a unique example of a medieval frontier Jewish quarter defined by complex urban planning, a synagogue, and various domestic units. Archaeological work allowed the recovery of a large number of animal remains. This paper deals with the results of the zooarchaeological study of this archaeofaunal assemblage, aiming to shed light on the ways in which animals were exploited, distributed, prepared and consumed by medieval Jewish population of Lorca. The results reveal a model of animal economy centered on the exploitation of caprines (sheep/goat) and, to a lesser extent, cattle, chickens and other secondary species, although the presence of non‐kosher species such as pigs and rabbit is noteworthy. The identification of butchery marks attributed to the porging of the hindquarters of caprines, a practice typical of medieval Jewish communities, represents a marker of ethno‐religious identity of great historical interest.
