Castile-La Mancha (Spanish Castilla-La Mancha) is an autonomous community of Spain.

Castile-La Mancha is bordered by Castile and León, Madrid, Aragon, Valencia, Murcia, Andalusia, and Extremadura.

Castile-La Mancha is composed of the provinces of Toledo, Ciudad Real, Cuenca, Guadalajara, and Albacete.

The capital of Castile-La Mancha is Toledo.

Castile-La Mancha was formerly grouped with the province of Madrid into New Castile ("Castilla la Nueva"), but with the advent of the modern Spanish system of semi-autonomous regions (las autonomías), it was separated due to great economic disparity between the capital and the remaining new-castilian provinces.

It is a common misunderstanding to assimilate Castile-La Mancha to its inner region La Mancha.
