Saint Seraphim of Sarov Cathedral, Zlatoust, Eastern Orthodox cathedral in Zlatoust, Russia.

Saint Seraphim of Sarov Cathedral is an Orthodox church in Zlatoust, Chelyabinsk Oblast, serving as the cathedral of the Zlatoust Diocese since 14 March 2017. Its rector is Bishop Pyotr of Zlatoust and Satka, and the key-keeper is Priest Andrei Tarasov. A bust of Emperor Nicholas II stands on the grounds, unveiled in September 2018.

The cathedral was built between 1997 and 1999, during a period when Orthodox churches were being rebuilt after Soviet rule ended. In March 2017, it became the central cathedral of the Zlatoust Diocese through an official church decree.

The cathedral serves as a center where the local Orthodox community gathers for worship and learning. The two choirs that sing during services help create a sense of shared faith among visitors and residents.

The cathedral stands in the centre of Zlatoust, near Yuri Gagarin Boulevard. It is an active parish with a Sunday school for adults and children, so visits are best timed outside service hours. Modest dress is expected inside.

A memorial bust of Emperor Nicholas II was installed in September 2018 to mark a century since the execution of the imperial family. This remembrance shows the link between the church and Russian historical memory.
