The MF 67 is a steel-wheel variant of electric multiple units used on Paris's Métro system. It is the most common Paris Metro rolling stock variant, being used on Lines 2, 3, 3bis, 5, 9, 10 and 12. 1482 cars have been built in 5 batches, first initially introduced on Lines 7 and 12.
On Lines 2, 5 and 9 the MF 67 is being replaced by the newer MF 2000 stock, as these aging trains are approaching 40 years old (the first deliveries were in 1967/1968). The trains underwent mid-life refurbishment from 1995 through 2007 (the trains on Line 3 were the last to be refurbished).

Conception [link]
It was originally envisioned by the RATP to convert all Metro lines to rubber-tyred pneumatic operation. However, this plan was later abandoned due to high costs, which in turn, would have prolonged the service of the aging Sprague-Thomson trainsets to 80 years. Therefore, a new class of steel-wheel rolling stock was developed.

Series [link]
The MF 67 actually comprises of seven different series trainsets, however two of the series trains were prototypes.
- Series A (now retired): 40 trains delivered to Lines 3 and 9 between 1967-1969
- One train in this series was that of the Zebulon, a stainless-steel prototype that never saw passenger service. It was used as a training train for many years until it succumbed to heavy vandalism in the late 2010s, it was scrapped as of 2011.
- Series B (now retired): 6 cars delivered in 1968 as prototype trains that never saw commercial service.
- Series C (now retired): 68 trains delivered to Lines 3 and 7 between 1972 and 1975.
- Series CX (now retired): 16 prototype cars that were fitted with "plug" type door openers, similar to that of the MF 77. These ran on Line 9.
- Series D: 363 cars that were originally deployed to Lines 3, 5, and 9 between 1973 and 1975. They now operate on Lines 3, 3bis, 9, 10, and 12.
- Series E: 56 trains that were originally deployed to 7bis, 8, and 13 between 1973 and 1975. They now operate on Line 10 (since the arrival of the MF 77 and MF 88).
- Series F: Deployed to Line 5 in 1974. Despite them being the newest series, they have suffered from excessive wear and tear (plus weather impacts due to them being stored in the outdoor Bobigny depot), they are now being replaced by the MF 2000.

Service Trains [link]
Currently, the RATP uses a string of MF-67 "Auteuil Convoy" trains (retired MF 67C trainsets from Line 2 in four car compositions), to supply the Auteuil and Vaugirard Depots, these trains are colored yellow and brown and serve as auxiliary equipment of the work of the RATP (VMI). They replaced the aging tractor variants of the Sprague-Thomson.
