Martos is a city and municipality of Spain belonging to the province of Jaén in the autonomous community of Andalusia.

As is essentially the case in the entire province of Jaén, the economy of Martos is heavily based on agriculture, specifically the cultivation of the olive tree.

French global automotive supplier Valeo established a factory in the city in the 1980s, making it the largest business in the province.

The city has been linked to the Roman settlement of Colonia Augusta Gemella, and starting in the 8th century was ruled by the Moors under various Islamic states for over 500 years.

During the Middle Ages, Martos became a strategic place, and its defences were reinforced with the construction of numerous fortifications in the city.

According to the National Statistics Institute of Spain, the city's population as of 1 January 2023 was 24,363 people, on a land area of 259.10 km2 (100 sq mi).

Despite this, PSOE has not governed in 2 legislative terms: 1995-1999, when the local Agrupación Progresista Independiente reached the office through a tripartite agreement that included the People's Party and Partido Andalucista, and 2011-2015, when Partido Andalucista and the People's Party agreed to share the mayorship (2011-2013 for PA and 2013-2015 for PP).
