Castilla-La Mancha, sometimes written in English as Castile–La Mancha, is a south-western European region that was part of the Kingdom of Castile. Nowadays it is established as an autonomous community of Spain. It is one of the most sparsely populated of Spain's autonomous communities. Albacete is the largest and most populous city. Its capital city is Toledo, and its judicial capital city is Albacete.

It is mostly in this region where the story of the famous Spanish novel Don Quixote by Miguel de Cervantes is situated, due to which La Mancha is internationally well-known. Although La Mancha is a windswept, battered plateau, it remains a symbol of Spanish culture with its vineyards, sunflowers, mushrooms, olive plantations, windmills, Manchego cheese, and Don Quixote.
