Cadet (French pronunciation: [kadɛ] ⓘ) is a station on Line 7 of the Paris Métro.

Cadet opened on 5 November 1910 with the commissioning of the first section of line 7 between Opéra and Porte de la Villette.

In 1982, a mosaic by the French artist, Hervé Mathieu-Bachelot, Lumière en éclats, was installed in the corridor leading to the platform towards La Courneuve–8 mai 1945.

The platforms are decorated using the colours and patterns of the flag of the United States, due to its location under rue La Fayette, which pays homage to the general who had fought alongside the Americans during the American Revolutionary War.

Hence, white, blue, and red beveled ceramic tiles line the walls of the vault, the ceilings, and at the ends of the platforms.
