Alésia (French pronunciation: [alezja]) is a station of the Paris Métro on line 4 in the 14th arrondissement situated in Petit-Montrouge quarter.

Recently this station has been retrofitted with platform screen doors, due to the RATP working on the line 4's automation.

This stop is featured in the animated films The Twelve Tasks of Asterix, in the chapter named Survive the Cave of the Beast.

Up until 2016, it was laid out in yellow Ouï-dire style with lighting strips, of the same color, supported by fake curved shaped consoles.

Since November 2018, the station's docks have been completely renovated, fitted with platform screen doors as part of the automation of Line 4.
