The TRF1, originally known as GIAT 155 mm Tracté (TR) is a 155mm French towed howitzer produced by Nexter (ex Giat Industries) and used by the French Army.

The TRF1 was showcased in 1979 at the Eurosatory arms trade show, as a replacement for Armée de Terre's BF-50. Giat produced it from 1984 to 1993.
