Tomelloso (Spanish: [tomeˈʎoso] ⓘ) is a municipality located in the northeast of the province of Ciudad Real, within the autonomous community of Castile-La Mancha in Spain.

The municipal territory is predominantly flat, except in the southeast, where the land gently rises to form the Campo de Montiel plateau.

The municipality is crossed only by the Córcoles and Záncara rivers (the latter forming the boundary with Pedro Muñoz), although several seasonal streambeds are evident during periods of heavy rainfall.

Tomelloso is first mentioned in historical records, specifically as "Los Tomillosos", during a visit by the Military Order of Santiago to Socuéllamos in 1494.

Today, the Posada de los Portales hosts rotating exhibitions across two of its three floors, which have been transformed into gallery spaces.

The Antonio López Torres Museum, designed by architect Fernando Higueras, was inaugurated in 1986 and is municipally owned.

This large structure is built using traditional materials and techniques, closely following the proportions and layout of authentic bombos still found scattered across the Manchegan countryside.

The bombo is a rural building, typical of Tomelloso and its surroundings, used to house farmers, their families, farming tools, and animals during fieldwork.

Spanning 1,700 square meters across four floors, the museum houses the permanent collection acquired over the years by the Virgen de las Viñas Cooperative through its cultural competition, along with temporary exhibitions.

Approximately thirty kilometers from Tomelloso, the Lagunas de Ruidera offer a unique and spectacular natural environment, both hydrologically and ecologically.
