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 Métro. The first MF 67 trains entered service on Line 3 in June 1968,^[3] and became one of the biggest orders for the Métro, with 1,482 cars has been 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 Métro 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 Métro lines (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.

Many of the 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 MF 67 remains in service on Lines 3, 3bis, 10 and 12, where the Île-de-France Mobilités intends to replace the remaining MF 67 trains with the MF 19.
