The Triumph Tiger 900 is a middle-weight dual-sport motorcycle introduced in 2020 by British manufacturer Triumph Motorcycles. While there was a motorcycle called the Triumph Tiger 900 (T400) manufactured from 1993 to 1998, this model is a completely new design intended as a successor of the Triumph Tiger 800 (which it has a similar appearance to).

Additionally, major updates were made to the suspension, and new Brembo disc brakes were added.
