Meco (Spanish: [ˈmeko] ⓘ) is a municipality in the eastern part of the Autonomous Community of Madrid, (Spain).

A town with a dry-soil agricultural tradition, Meco has long been an exporter of wheat, flour and bread to Alcalá, Guadalajara, and Madrid.

After the re-conquest of the Media Marca (Middle March) by Alfonso VI, it came to form part of the Commune of Villa and Land of Guadalajara.

The son of Iñigo López de Mendoza, also of the same name, added the title of Marquis of Móndejar by buying this villa from the Catholic Monarchs.

Among the buildings of the town, a magnificent parish Church of Nuestra Señora de la Asunción (Meco) stands out.

A hall church with columns, its design has been attributed to Rodrigo Gil de Hontañón by some historians.
