Stadtpfarrkirche, Roman Catholic parish church in Linz, Austria.

The Stadtpfarrkirche is a parish church in Linz whose nave was laid out in 1207 along the sunrise over the Pfenningberg. A Gothic choir and tower followed in the 15th century, and from 1649 to 1653 a Baroque rebuild gave it three naves, re-vaulted by 1656. The tower's present helm dates from 1823.

The church was laid out in 1207 during the founding survey of Linz's town extension, when the new walls, the Hauptplatz and the church were staked out together. Its nave axis was set at sunrise on Good Friday, 20 April 1207, and the choir axis at sunrise on Easter Sunday, 22 April 1207. A Gothic choir followed in 1448 and the tower in 1453; from 1649 to 1653 a Baroque rebuild re-vaulted the nave and choir, consecrated in 1656.

The high altar design is by Matthias Ludwig Krinner and Johann Kaspar Modler (1771); Johann Carl von Reslfeld painted its altarpiece of the Assumption of Mary in 1695. Side altars carry paintings by Joachim von Sandrart and Bartolomeo Altomonte, and the Floriani altar holds a copy of a Linz town view painted around 1860 showing the city about 1694, with the church's Baroque onion dome visible.

The church is open daily for visitors to explore the interior at their own pace. Those wishing to attend services should check current times in advance and dress respectfully for the religious setting.

Emperor Friedrich III died in Linz in 1493, and his heart and entrails were walled into an urn in the church's chancel, while his body was buried in Vienna. A red marble gravestone with his coat of arms marks the spot. The church also preserves the axis kink between nave and choir, set out from sunrise points in April 1207.
