État 141-001 to 141-250 was a series of 2-8-2 steam locomotives of the Chemins de Fer de l'État.
The series of 250 engines, numbered 141-001 to 141-250 were built in 1921. They were renumbered 141.B.001 to 141.B.250 by the SNCF in 1938 and ended their career in the West of France at the end of the 1960s.

The engines were capable of a speed of up . Their light weight per axle made them capable of hauling both passenger and goods trains on most of the Chemins de Fer de l'États network and of the former Chemins de Fer de l'Ouest. Due to the need of a simple to operate and solid locomotive, the Chemins de Fer de l'État even went to choose the pressure of the boiler (or in French). The pressure was 12 kp/cm2 or 12 hectopièzes (old units of measurement, 1.2 MPa in modern units), this enabled the machine to develop an output of 1540hp at 60 km/h and 830hp at 100 km/h. From 1932 the timbre was increased to 14 kp/m2 to obtain a power of 1700hp at 60 km/h and 1160hp at 100 km/h; locomotives were recoded from "B" to "C" as this work was done.
141.C.50 was rebuilt at Sotteville-lès-Rouen in 1928. This depot was built by the British and was the largest of the Chemins de Fer de l'Ouest (part of the État from 1908). There it received new Renaud type valves, saving 9.8% coal. It also received a Kylchap exhaust.
One locomotive has been preserved: 141.C.100 (and tender 22.B.609) are in working order and are listed as a Monument historique.
