The Ascension Cathedral is a Russian Orthodox church in Novocherkassk, Rostov Oblast, Russia. It used to be one of the largest churches of the Russian Empire and the main church of the Don Host Province.
The five-domed building, which stands 75 meters tall, is a notable example of the Russian Neo-Byzantine architecture. It was erected between 1891 and 1904 on the site of an earlier church. The first church on the site was built to Luigi Rusca's designs. It collapsed in 1846.
