Montmartre (UK: mon-MAR-trə, French: [mɔ̃maʁtʁ] (listen)) is a large hill in Paris's northern 18th arrondissement. It is 130 m (430 ft) high and gives its name to the surrounding district, part of the Right Bank. Montmartre is primarily known for its artistic history, for the white-domed Basilica of the Sacré-Cœur on its summit, and as a nightclub district.

The other church on the hill, Saint Pierre de Montmartre, built in 1147, was the church of the prestigious Montmartre Abbey. On 15 August 1534, Saint Ignatius of Loyola, Saint Francis Xavier and five other companions bound themselves by vows in the Martyrium of Saint Denis, 11 Rue Yvonne Le Tac, the first step in the creation of the Jesuits.

Near the end of the 19th century and at the beginning of the 20th, during the Belle Époque, many artists lived, worked, or had studios in or around Montmartre, including Amedeo Modigliani, Claude Monet, Pierre-Auguste Renoir, Edgar Degas, Henri de Toulouse-Lautrec, Suzanne Valadon, Piet Mondrian, Pablo Picasso, Camille Pissarro and Vincent van Gogh. Montmartre is also the setting for several hit films.

The area is served by Métro, with Line 2 stations at Barbès–Rochechouart, Anvers, Pigalle and Blanche, Line 4 stations at Château Rouge and Barbès–Rochechouart, as well as Line 12 stations at Pigalle, Abbesses, Lamarck–Caulaincourt and Jules Joffrin. It is also served by the Montmartre Funicular. The historic district established by the City of Paris in 1995 is bordered by Rue Caulaincourt and Rue Custine on the north, the Rue de Clignancourt on the east and the Boulevard de Clichy and Boulevard de Rochechouart to the south, containing 60 ha (150 acres).
