St. Florian's Church (Slovene: Cerkev svetega Florijana, Šentflorjanska cerkev) is a Roman Catholic church at Upper Square (Gornji trg) in Ljubljana, the capital of Slovenia. It was completed in 1696. It is a local church that belongs to St. James's Parish.

When the Jesuit order was re-established in Slovenia in 1870, St. Florian's became a center of Jesuit activity.
