Lamarck — Caulaincourt (French pronunciation: ​[lamark colɛ̃kuʁ]) is a station on Line 12 of the Paris Métro in the Montmartre district and the 18th arrondissement of Paris.

Lamarck — Caulaincourt is located in within the 18th arrondissement of Paris, which covers some of the northern-most parts of the city. Specifically, it runs beneath Rue de la Fontaine du But where it changes into a staircase. The station takes its name from the two main roads that cross near its entrance: Rue Lamarck and Rue Caulaincourt.

The station opened on 31 October 1912 as part of a northward extension of the Nord-Sud company's Line A from Pigalle to Jules Joffrin. In 1930, the Compagnie du chemin de fer métropolitain de Paris (CMP) bought out the Nord-Sud company and renamed Line A to Line 12 in order to conform to the former's convention.

Originally named Constantin Pecqueur, after the short street at the top of the entrance stairway, which in turn derives its title from the socialist economist of the same name, Lamarck — Caulaincourt opened as Lamarck, a reference to Rue Lamarck, the road at the bottom of the entrance stairwell. At a later time, the station's name changed to Lamarck (Caulaincourt), and finally received its current spelling of Lamarck — Caulaincourt. Rue Lamarck is dedicated to Jean-Baptiste Pierre de Monet, Chevalier de Lamarck (1744–1829), a French naturalist who is mainly remembered for his theory of the inheritance of acquired traits. Rue Caulaincourt is named after the marquis Armand Augustin Louis de Caulaincourt (1773–1827), general, ambassador and Foreign Minister from 1813 to 1814.
