The AnsaldoBreda -Ansaldo STS Driverless Metro is a class of driverless electric multiple units and corresponding signaling system. Manufactured by AnsaldoBreda and Ansaldo STS in Italy, it is or will be used on the Copenhagen Metro, Princess Nora bint Abdul Rahman University, the Brescia Metro, the Thessaloniki Metro, Line 5 of the Milan Metro, Line C of the Rome Metro and the Yellow Line of the Taipei Rapid Transit System. The first system to use this class of driverless electric multiple units was the Copenhagen Metro which opened in 2002.

The rolling stock consists of two to six articulated cars. All trains are 2.65 meters (8.7 ft) wide, except those used on the Rome Metro which are 2.85 meters (9.4 ft) wide. All operate on standard gauge. Each car has a power output of 210 or 256 kilowatts (282 or 343 hp), fed from a third rail at 750 volts (except in Rome where it is 1,500 V overhead line). The systems are fully automated, consisting of automatic train protection (ATP), automatic train operation (ATO) and automatic train supervision.

The rolling stock uses standardized car bodies, articulated together. The number of cars varies across the different systems where they are used. The trains used on the Princess Nora bint Abdul Rahman University system are two car units. For the other systems, the units vary between three and six cars, making the trains from 39 to 109 meters (128 to 358 ft) long. They are 2.65 meters (8.7 ft) wide, except the Rome Metro units, which are 2.85 meters (9.4 ft). The units vary from 3.4 to 3.85 meters (11 ft 2 in to 12 ft 8 in) tall. Each car has two doors on each side, which are 1.3 meters (4 ft 3 in) wide and 1.945 meters (6 ft 4.6 in) tall. The vehicles are designed by Giugiaro Design.
