The Corpus Christi Basilica (Polish: Bazylika Bożego Ciała), located in the Kazimierz district of Kraków, Poland, is a Gothic church founded by King Casimir III the Great in 1335.

It was intended as a monastery church, which explains the large plot of land on which it stands, and the presence of a monastic cemetery next to it.

In 1404 King Władysław II Jagiełło gave it to the Canons Regular of the Lateran, a congregation which he had brought in from Kłodzko.

The church was robbed clean and the interior utterly devastated by soldiers of the 1655 Swedish invasion (the Deluge),[2] which explains the prevalence of Baroque in its current decoration.
