The AVE Class 100, or Series 100, is a high-speed train used for AVE services by the RENFE, in Spain. It was the first high-speed train put into service in Spain, in 1992.

This class lived through all the changes involved in the creation of the Spanish high-speed network; originally the plan was to build the high-speed route to Andalusia on an Iberian gauge track (1,668 mm (5 ft 5 ²¹⁄₃₂ in)). At the last minute, it was decided that it should be 1,435 mm (4 ft 8 ¹⁄₂ in) standard gauge, meaning RENFE changed its original order for 24 Iberian gauge units to sixteen standard gauge ones, which were delivered between 1991 and 1993.

After various changes in the contract with Alstom and compensation for delays the final eight were delivered; two standard gauge sets and 6 Iberian gauge sets. The Iberian sets became the RENFE Class 101 () which used to operate the Euromed services along the Mediterranean corridor (this route is now covered by the RENFE Class 130 trains).

The train 100015 set one of the most important speed records in Spain, reaching 356.8 kilometres per hour (221.7 mph) on a test run. Its previous record had been 330 km/h (210 mph) on an earlier test run. The Class 100 was also involved in speed tests using Talgo carriages.

This class has almost exclusively served the Madrid–Seville high-speed rail line. They were used on the Madrid–Barcelona high-speed rail line for a short period until introduction of the RENFE Class 102. The units used on the Barcelona line had to have their pantographs changed as well as installation of the ERTMS system.
