Mariestad Cathedral, Gothic cathedral in Mariestad, Sweden.

Mariestad Cathedral is a late-Gothic hall church built 1593–1619, with a single broad nave and only hinted transepts, pointed-arch windows and buttresses. Its tower, topped by a slender spire flanked by two smaller spires, reaches 82.5 metres. The walls are light reddish-brown unplastered natural stone and the roofs dark grey; the exposed stonework and spire date from Folke Zettervall's 1905 restoration, before which the church was plastered. Inside are white cross vaults on clustered pillars, a brass chandelier, and a Baroque altarpiece of 1701 by Börje Löfman.

Mariestad was founded in 1583 by Duke Charles and became an ecclesiastical centre two years later; the church was built from 1593 to 1619. From 1580 to 1646 the town housed a superintendent covering northern Västergötland and Värmland, moved to Karlstad in 1646. A royal letter of 9 January 1696 ruled the church was no longer to be regarded as a cathedral.

The name 'cathedral' survives from Mariestad's years as a superintendent seat, 1580–1646, though a royal letter of 9 January 1696 ruled the church was no longer to be regarded as one. Since 1972 the tower's 20-bell carillon has played hymns recorded by organist Anders Börjesson at 9, 12, 15 and 18, changed with the church year and season.

The church stands high in the old town (Gamla stan), next to Norra skolan, the town's first school, now converted into housing. The tower carillon plays hymns recorded by organist Anders Börje­sson four times a day, at 9, 12, 15 and 18, and the hymns change with the church year and season. The carillon was installed in 1972 and has 20 bells; the church also has three church bells.

The tower reaches 82.5 metres, making it Mariestad's tallest building and Sweden's tenth-highest church tower. Since 1972 a carillon of 20 bells has played hymns recorded by organist Anders Börjesson at 9, 12, 15 and 18 o'clock, changed with the church year.
