Campo Formio (French pronunciation: [kɑ̃po fɔʁmjo]) is a station on Line 5 of the Paris Métro, located in the 13th arrondissement of Paris, under the Boulevard de l'Hôpital.

The station opened on 6 June 1906. The name refers to neighbouring Rue de Campo-Formio, named for the Treaty of Campo Formio signed in 1797 between France and Austria. France obtained Belgium, part of the left bank of the Rhine, the Ionian Islands, as well as the recognition of the Cisalpine Republic. German bombing in World War I damaged the station in 1918.

During the summer of 2007, the station was the provisional terminus of Line 5 following the closure of the platforms at the Place d'Italie station and the construction of the Boucle d'Italie.

In 2018, 1,369,978 travellers entered the station which placed it at 285th position of Métro stations for its attendance.

The station is located under the Boulevard de l'Hôpital on the corner of the Rue de Campo-Formio.
