Holy Trinity Church in Troitskaya Sloboda, Eastern Orthodox church in Meshchansky District, Moscow, Russia.

The Holy Trinity Church in Troitskaya Sloboda is a stone Orthodox church at 2nd Troitsky Lane, 8, building 1, near the Samotyok River. Its refectory was extended in 1851 with a side chapel of the Vladimir Icon of the Mother of God, designed by architect Alexey Martynov. The church is the Moscow metochion of the Trinity-Sergius Lavra and belongs to the Sretensky Deanery of the Moscow City Diocese.

The wooden church with a side chapel of Sergius and Nikon of Radonezh was built in 1633 and rebuilt in 1688, still in wood. In 1696 the wooden church was dismantled and a stone one erected in its place. The chapel of the Vladimir Icon of the Mother of God was added to the refectory in 1851 to a design by architect Alexey Martynov. The metropolitans' chambers on the podvorye were built in 1760–1767 to a design by Vasily Yakovlev.

The church serves as an extension of the Troitse-Sergiyeva Lavra monastery and remains an active place of worship for the Orthodox community in Moscow. Visitors can observe religious practices and the role this location plays in the spiritual life of the neighborhood.

The church stands at 2nd Troitsky Lane, 8, building 1, in the Meshchansky District; the address is not 8/10. The grounds also hold the metropolitan chambers, whose house church of the Moscow Hierarchs was restored and first used for liturgy on 23 June 2011. The church is active, so check service times before visiting.

The building displays a rare mix of Western European Baroque style and Russian building traditions, setting it apart from other churches of its era. This fusion reflects a moment when Moscow was absorbing European influences into its sacred architecture.
