Fuenlabrada is a city and municipality of Spain located in the Community of Madrid. As of 2018, it has a population of 193,586, making it the region's fourth most populated municipality. The etymology of Fuenlabrada comes from the contraction of Fuente Labrada, Spanish for "carved fountain".

The highest point in the municipality (721 metres above sea level) is located in a hill to the northwest of the city proper. The city proper's altitude gently decreases from the Northwest to the Southeast; the lowest areas in the municipality (slightly over 600 metres above sea level) are located in the East, past the A-42 near the border with Getafe.

The southeast of the municipality is covered by the Polígono Cobo Calleja [es], a huge economic area overwhelmingly dedicated to the wholesale distribution of Chinese imports (considered the biggest one in Europe in the latter regard).

The residential area of Loranca [es] (203.6 ha in size) lies in the west, near Móstoles, semi-detached from the main urban nucleus by the M-407 [es] highway.

The main hydrographic feature is the Arroyo Culebro [es], a tributary of the Manzanares. Other parts of the municipality (including the Arroyo de Fregacedos) are however part of the Guadarrama catchment area.
