The Z-TER (Z 21500) is a French model of electric multiple unit regional passenger train, manufactured by Alstom and Bombardier Transportation, and operated by SNCF.

They are used on regional links, and can be coupled with another Z-TER. They are derived from the French diesel passenger regional train "X-TER" (X 72500), and is the first regional train to reach 200 km/h.

Their main characteristic is their ability to travel at 124.27 mph, which constitutes a first for TER self-propelled equipment. This ability, used every day over several sections of conventional lines, is also operated for the first time on a high speed line since 2017. This is a first in France, thanks to a adaptation of eight of these elements to signaling specific to LGVs, then renumbered as Z 21700.

As other regional trains, they are owned by the French regions, and are dispatched as :

• 19 "Pays de la Loire" region^[2]
• 15 "Centre" region^[2]
• 6 "Aquitaine" region^[2]
• 17 "Bretagne" region^[2]
