Holy Trinity church in Alapayevsk, Russian Orthodox church in Alapayevsk, Russia.

Holy Trinity Church in Alapayevsk is a Russian Orthodox building with white stone walls and multiple domes reflecting the regional architectural style. The structure displays traditional Orthodox design elements with a clear composition that is immediately visible from outside.

Residents of Alapaikha and nearby villages petitioned the Tobolsk eparchy for their own church, since the Murzinsky parish lay 50 versts away. In 1702 they built a small stone church dedicated to St Alexius at their own expense. A stone side chapel of Archangel Michael followed in 1771, consecrated in 1776 by Archimandrite Isaiah of the Nevyansk Epiphany Monastery. The Trinity church was added from 1793 and consecrated in 1816 after an 1798 fire destroyed the wooden roofs.

The cathedral is the seat of the Alapayevsk Eparchy, a status tied to the 1912 Synod decision. Its name comes from the Holy Trinity side chapel consecrated in 1816, after a 1798 fire delayed construction. The building housed a bakery from 1932 to 1992, and restoration began in 1991.

The cathedral stands in the centre of Alapayevsk, on the site of the 1702 Alexis church; the bell tower rebuilt in 1832–1833 lost its spire in the storm of 20–21 March 2016. The crypt on the south side of the altar, bricked up in 1918, was restored by the late 1990s. Since 1992 the building has served as a bishop's metochion.

The cathedral's bell tower lost its spire in a storm that hit Yekaterinburg on the night of 20–21 March 2016. The building also held a bread factory from 1932 to 1992, before restoration began in 1991.
