The Hoya of Guadix (Spanish: Hoya de Guadix) is a natural plain in the northern part of the province of Granada, Andalusia, Spain. It covers some 500 square kilometres (190 sq mi), and is formed by the basins of the rivers Fardes and Guadix. It is surrounded by the heights of the Sierra Nevada to the south, the Sierra de Baza to the east, the Sierra Mágina to the north and the Sierra Harana to the west. It is separated by the Cerro Jabalcón from the Hoya of Baza which, like the Hoya of Guadix, is one of the series of valleys forming the Surco Intrabético.

Hoya in this context refers to a low-lying plain or basin.
