The border of Granada (frontera de Granada in Spanish) was a border region that existed between the Nasrid kingdom of Granada and the kingdoms of Murcia, Jaén, Córdoba and Seville following the integration of those former Muslim territories within the Crown of Castile in the mid-13th century. The delineation of this border region underwent several changes subsequently, but on the death of Alfonso XI in 1350, the Granadine border was fixed geographically, in general terms, until the beginning of the Granada War in the late 15th century. This territory was also referred to as La Banda Morisca (The Moorish Strip). Toponymy Several modern place names survive that relate to the frontier between Granada and Christian Andalusia and the communities established on the Castilian side of the border. Thus, in the province of Cadiz there are the municipalities of Arcos de la Frontera, Castellar de la Frontera, Chiclana de la Frontera, Conil de la Frontera, Jerez de la Frontera, Jimena de la Frontera and Vejer de la Frontera; in the province of Malaga, Cortes de la Frontera; in the province of Cordoba, Aguilar de la Frontera and in the province of Sevilla, Morón de la Frontera. There are other municipalities in the Huelva province, which include "de la Frontera" in their names. However, these do not refer to the Border of Granada border, but to the border with Portugal. This is the case with Rosal de la Frontera and Palos de la Frontera.

The border then went through modifications during the reigns of Sancho IV, Fernando IV and Alfonso XI. However, following the death of Alfonso XI in 1350, the border of Granada underwent a process of stabilization and delineation, which lasted until the War of Granada at the end of the 15th century. The line of the border ran from a point on the Strait of Gibraltar, between the mouths of the Rio Palmones and the Rio Guadarranque climbing northwards through the Sierra de Montecoche until it arrived at the Guadalete River. At that point, it veered eastwards, running parallel to the northern foothills of the Serranía de Ronda. From the Guadalteba and Yeguas rivers, the border took a north-west
