Saint George's Cathedral, Eastern Orthodox cathedral in Novi Sad, Serbia.

Saint George's Cathedral is an Eastern Orthodox cathedral in Novi Sad, Serbia, built between 1860 and 1880 on the ruins of an older church, with further work completed by 1905 under architect Milan Michal Harminc. Its interior has an iconostasis with 33 icons painted by Paja Jovanović, and stained-glass windows installed in 1905 by Budapest artist Imre Zseller.

A Baroque church was begun in 1720 and enlarged in 1734; it burned down in a bombing in 1849 during the Revolutions in the Habsburg lands. Planning for the present cathedral started in 1851, and it was built between 1860 and 1880 on the ruins of the old church. Further renovation and completion followed by 1905 under the architect Milan Michal Harminc, during the office of Bishop Mitrofan Šević, when a new tower with bells from Budapest was added.

The cathedral is dedicated to Saint George, and its iconostasis holds 33 icons painted by Paja Jovanović, considered among his best ecclesiastical works. Above both choirs hang his historical paintings of the coronation of Stefan the First-Crowned and Saint Sava pacifying his brothers Vukan and Stefan.

The cathedral stands on Nikola Pasic Street in central Novi Sad, next to the Bishop's Palace, and is easy to reach on foot from the main square. It is an active place of worship, so access to some areas may be limited when services are in progress.

In the cathedral courtyard stands a Theophany Cross from the 18th century, recognized as the oldest surviving monument in the city. It predates the current building and was already here before the original church was destroyed and rebuilt.
