The MF 67 (French: Métro Fer appel d'offres de 1967; English: Steel-wheeled metro ordered in 1967) is a fleet of steel-wheel electric multiple unit trains for the Paris Metro. The first MF 67 trains entered service on Line 3 in July 1968, and became one of the biggest orders for the Metro, with 1,482 cars constructed. The need to replace the Sprague-Thomson fleet, as well as increasing costs associated with the later-cancelled plan to introduce rubber-tyred trains on all Metro lines, were the main factors for the size of the order.

At its peak, during the late 1980s and the early-1990s, the MF 67 operated on eight of the (then) fifteen Metro lines (2, 3 and 3bis, 5, 7bis, 9, 10 and 12): the MF 67 also operated on Lines 7, 8 and 13 (including the old Line 14), all before the introduction of the MF 77 in 1978.

Between 2004 and 2007, the Line 3 sets have been deeply refurbished, adding new lighting, a forced ventilation system, a new black front, rearranged seating, automated announcements, stop indicator lights and door warning lights above the doors. A more moderate refurbishment were done on the trains on lines 3 bis and 9, adding a new black front similar to the ones on line 3 and replacing the old bench seats with single seats. However, sets 129 and 130 from line 12 were transferred to line 3 in 2012 and weren’t renovated, as the renovation of the cars had ended in 2007, thus making them the only non-renovated MF67 sets to run on line 3.

Many MF 67 trains have been removed from service: throughout 1994, the MF 88 displaced the MF 67 from Line 7bis, and from 2008 to 2016, the MF 01 replaced the MF 67 on Lines 2, 5, and 9. The newer MF 67 trains from line 9 were transferred to lines 10 and 12, replacing some of the older MF 67 trains on those lines. The MF 67 remains in service on Lines 3, 3bis, 10 and 12.

As of 2026, they are the oldest trains running on the Metro and their replacement is scheduled between 2025–2034, where the Île-de-France Mobilités intends to replace the remaining MF 67 trains with the MF 19. Replacements began on line 10 in 2025, and will continue with lines 3bis in 2027, 12 in 2028 and 3 in 2031. Line 3 in particular was the first line to receive the MF67 and will be the last line to retire them, being served by the MF 67 continuously for approximately 65 years, rivaling the longevity of the Sprague Thomson trains that ran on Line 2 and 5 for approximately 70 years.
