Church of the Holy Mandylion, Eastern Orthodox church building in Kukoboy, Yaroslavl Oblast, Russia.

The Church of the Holy Mandylion is a five-domed, cross-in-square Orthodox church of four pillars and three apses, square in plan and raised on a lower storey. A tent-roofed bell tower adjoins it on the west, and the walls are faced in light brick with turquoise brick on the tents. Profiled kokoshniks, arched stained-glass windows and bands of coloured tiles decorate the facades.

The church was founded in 1909 and completed in early 1912 by local craftsmen for merchant Ivan Agapovich Voronin, a native of nearby Ryabinki who had made his fortune in Saint Petersburg. Villagers chose the church over a railway line to Poshekhonye. Architect Vasily Kosyakov designed it, and it cost one million rubles. Consecrated in May 1912 by Bishop Tikhon, later Patriarch of Moscow.

The main altar is dedicated to the Holy Mandylion, the north altar to Saint Nicholas and the south one to the Kazan Mother of God. Villagers chose a church over a railway from Kukoboy to Poshekhonye when the merchant Ivan Voronin offered them the choice. The church was consecrated in May 1912 by Bishop Tikhon of Yaroslavl and Rostov, later Patriarch of Moscow and All Rus'.

The church stands in Kukoboy, in the Pervomaysky District of Yaroslavl Oblast. Restoration work has been suspended for lack of funds, so the interior may be closed or partly inaccessible; ask locally before planning a look inside. The building is a regional cultural heritage site.

The church was built with white facing brick and turquoise brick for the bell towers, both brought from Finland; a small brickworks was set up on site for the job. The merchant Ivan Voronin paid about 1,000,000 rubles, and the church was consecrated in May 1912 by Bishop Tikhon, later Patriarch of Moscow and All Rus'.
