Convention (French pronunciation: [kɔ̃vɑ̃sjɔ̃] ) is a station on line 12 of the Paris Métro in the 15th arrondissement. It is named after the nearby rue de la Convention, in turn named after the National Convention, an assembly that sat from 1792 to 1795.

The station opened on 5 November 1910 as part of the original section of the Nord-Sud Company's line A between Porte de Versailles and Notre-Dame-de-Lorette. On 27 March 1931, line A became line 12 when It was taken over by the Compagnie du chemin de fer métropolitain de Paris (CMP), incorporating it into the Paris Métro.

Like most stations along the line, the platforms were modernised with the installation of green metal casings on the walls from the 1950s, subsequently repainted in blue.

As part of the "Un métro + beau" programme by the RATP, the station's corridors were renovated and modernised on 17 January 2003.

In 2019, the station was used by 5,275,717 passengers, making it the 76th busiest of the Métro network out of 302 stations.

In 2020, the station was used by 2,674,415 passengers amidst the COVID-19 pandemic, making it the 67th busiest of the Métro network out of 304 stations.

In 2021, the station was used by 3,734,750 passengers, making it the 67th busiest of the Métro network out of 304 stations.
