Reuilly–Diderot (French pronunciation: [ʁœji didʁo]) is a station on lines 1 and 8 of the Paris Métro in the 12th arrondissement.

On 5 May 1931, line 8's platforms opened as part of its extension from Richelieu–Drouot to Porte de Charenton.

In the 1930s, the platforms of line 1 were extended to 105 metres to cater for 7-car trains, a plan which ultimately did not materialise.

As part of the "Un métro + beau" programme by the RATP, the station's corridors and platform lighting were renovated and modernised on 31 March 2008.

[2] This was for the installation platform screen doors to improve passenger safety and for automation, which were done in March 2011.
