The MP 73 (French: Métro Pneu appel d'offres de 1973; English: Rubber-tyred metro ordered in 1973) was a rubber tired variant of electric multiple units used on the Paris Metro Line 6. Put into service in 1974, it is similar to the MP 59 performance-wise, with the appearance of the MF 67. It constitutes, after the MP 51, the MP 55, and the MP 59, the fourth Parisian generation of rubber-tired metros.
The MP 73 was replaced by the MP 89 on Line 6 between 2023 and 2026. Their final service before retirement occurred on 8 July 2026.
