The Church of the Holy Cross (Polish: Bazylika Świętego Krzyża) is a Roman Catholic house of worship in Warsaw, Poland.

Located on Krakowskie Przedmieście opposite the main Warsaw University campus, it is one of the most notable Baroque churches in Poland's capital.

In 1653 Queen Marie Louise Gonzaga gave the church to the French order of Missionary Friars of Vincent de Paul.

[2] During the Warsaw Uprising of 1794, the stairs leading to the main entrance were destroyed and had to be replaced with new ones designed by Chrystian Piotr Aigner.

[2] During the Partitions, the church gained much importance, especially after the 1861 demonstration held before it, which was brutally put down by Russian Cossack troops — sparking the January 1863 Uprising.

On Christmas Day 1881, an outbreak of panic following a false alarm of fire in the crowded church caused the stampede deaths of twenty-nine persons.

[2] In 1889 the external staircase leading to the main entrance was reconstructed, and a sculpture of Christ Bearing His Cross by Pius Weloński was added.

In addition to urns containing the hearts of some of Poland's most renowned artists, there are several epitaphs to other notable Poles of the late 19th and early 20th centuries, including Juliusz Słowacki, Józef Ignacy Kraszewski, Bolesław Prus, and Władysław Sikorski.
