The CAF Urbos is a family of trams, streetcars, and light rail vehicles built by CAF. As of 2026, over 1,900 Urbos trams operate in over 50 cities worldwide. The Spanish manufacturer CAF previously made locomotives, passenger cars, regional, and underground trains. In 1993, CAF started building trams for Metrovalencia, with the delivery of 16 trams until 1999. This was a variant of a Siemens design and some components were delivered by Siemens, including bogies and traction motors. This design was also sold to Lisbon Trams in 1995; CAF then decided to design and build the Urbos in-house.

There are three generations of the CAF Urbos, namely the Urbos 1, Urbos 2, and Urbos 3. The first generation was ordered by the Bilbao tram operator, who received eight trams between 2002 and 2004. The second generation was sold to other operators in Spain, and the third generation is sold in Spain, elsewhere in Europe, the United States, Australia and in the UK. Manufacturing locations include Beasain, Zaragoza and Linares, Spain; Elmira, New York, USA; Hortolandia, Brazil; Newport, UK; Huehuetoca, Mexico; and Bagnères-de-Bigorre, France.
