Since June 2019, the current mayor is Alberto Rojo Blas (Spanish Socialist Workers' Party). Demographics Urban area The 2020 report on urban areas in Spain published by the Ministry of Transports, Mobility and Urban Agenda identifies an urban area formed by the municipality of Guadalajara together with the neighbouring municipalities of Azuqueca de Henares, Alovera, Cabanillas del Campo, Marchamalo, Villanueva de la Torre and Chiloeches, with a population of 161,683 (2019).

It has several historic buildings such as the Palacio del Infantado, as well as many churches, such as the church of San Ginés.

Very close to this church, is placed the chapel known as "Capilla de Luis de Lucena", which has several fresco paintings on its walls and ceiling. The Church of los Remedios was declared Bien de Interés Cultural in 1924, and currently serves as the auditorium of the University of Alcalá. The Church of la Piedad was declared Bien de Interés Cultural in 1931. Before the Civil War, Guadalajara was also known to be among the cities with most number of antique azulejos in the Iberian Peninsula housed in their buildings, since the city housed the largest collection of azulejos from Talavera de la Reina pottery; now almost all of those azulejos are lost.

In Taracena there is the 17th century Church of the Immaculate, in a very simple Renaissance style. In Usanos, there is the 13th-century
