Marcel Sembat (French pronunciation: [maʁsɛl sɑ̃ba]) is a station of the Paris Métro.

It is named after the nearby place Marcel Sembat which was named after the journalist Marcel Sembat (1862–1922) who was a director of the socialist review La Petite République from 1892 to 1897 and husband of the painter Georgette Agutte from 1897 until their deaths in 1922.

He was also the Minister of Public Works from 1914 to 1916 as well as socialist deputy for the 18th arrondissement of Paris's Grandes-Carrières district from 1893 till his death in 1922.

Hence, it is one of the first three stations to provide service to the inner suburbs of Paris (along with Billancourt and Pont de Sèvres).

As part of the "Renouveau du métro" programme by the RATP, the station's corridors was renovated and modernised on 23 April 2004.
