Leonhardkirche, Gothic parish church in St. Leonhard district, Graz, Austria

The Leonhardkirche is a parish church in Graz that combines Gothic features with a Baroque facade and was expanded with a modern eastern extension around 1960. The building includes an adjoining cemetery and continues to serve as an active parish center with offices and administrative space for the community.

The original structure was first mentioned in 1361 as Sankt Lienhart and was replaced by a new building in 1433, consecrated by the Archbishop of Salzburg. The church underwent several transformations, including Baroque modifications and a modern expansion in the 20th century.

Saint Leonard was chosen as patron because he protects livestock, especially horses, and the Strata hungarica, a trade road once used by horse-drawn carts, ran past the church. Until the 18th century the church held a double dedication to Leonard and Mary; then Leonard became sole patron. The west portal's sandstone figures, attributed to Veit Königer, show Leonard with prisoners, as he is also their patron.

The church stands on the busy Elisabethstraße/Gleisdorfer Straße B65, opposite the LKH Graz hospital. The parish house, the Seydler-Haus and the 1990 parish centre sit next to it on Leonhardstraße, followed by the Odilien-Blindeninstitut. The St. Leonhard cemetery adjoins the south and east sides, where the grave monuments and Prokesch-Osten's domed mausoleum by Theophil Hansen can be visited.

Until 1818, a Roman-era grave stele was built into the church's outer wall before being transferred to Eggenberg Palace's archaeological museum. This discovery shows the ancient roots beneath the area and was later carefully preserved and documented.
