The Chronica latina regum Castellae, known in Spanish as the Crónica latina de los reyes de Castilla, both meaning "Latin Chronicle of the Kings of Castile", is a medieval Latin history of the rulers of Castile from the death of Count Fernán González in 970 to the reconquest of Córdoba by King Ferdinand III in 1236–39.
It was designed with two purposes: for use at the royal court as a speculum principis and to defend the interests of Castile against those of the Kingdom of León.
Modern historians disagree whether the continuation down to the capture of Córdoba six years later was written by Juan de Soria or by another author.
He makes little use of other narrative histories, which were the main sources of the contemporary chronicles called Chronicon mundi and De rebus Hispaniae.
The Chronica is preserved in only one late fifteenth-century manuscript, MS G-1 or 9/450, in the library of the Real Academia de la Historia in Madrid.
