The Basilica of the Sacred Heart of Paris, commonly known as Sacré-Cœur Basilica and often simply Sacré-Cœur, is a Roman Catholic church and minor basilica in Paris, France, dedicated to the Sacred Heart of Jesus.

Sacré-Cœur Basilica is located at the summit of the butte Montmartre, the highest point in the city. It is a popular landmark, and the second-most visited monument in Paris. The basilica was designed by Paul Abadie.  Construction began in 1875 and was completed in 1914. It is considered as both a political and cultural monument, representing a national penance for the defeat of France in the 1870 Franco-Prussian War and for the actions of the socialist Paris Commune of 1871. Sacré-Cœur Basilica was built in a neighborhood which witnessed significant events by the Paris Commune of 1871.

The basilica is accessible by bus or metro. Sacré-Cœur is open from 06:00 to 22:30 every day. The dome is accessible from 09:00 to 19:00 in the summer and to 18:00 in the winter.
