Trinity Cathedral, Orthodox cathedral in Troieshchyna district, Kyiv, Ukraine.

Trinity Cathedral is a five-domed, cross-shaped Orthodox cathedral with three apses, built in 1997 to designs by Vadim and Iryna Grechyna. It stands on an artificial hill between the village of Troieshchyna and the Vyhurivshchyna-Troieshchyna housing estate. Its separate four-tier bell tower rises beside it, and the interior holds a seven-tier, 15.2-metre-high carved iconostasis.

The foundation stone was laid on 16 October 1990, with construction beginning in 1991 under the patronage of Metropolitan Volodymyr. The project was funded by donations, including the sale of schemarchimandrite Seraphim Sobolev's apartment on Andriivskyi Descent. The cathedral was consecrated on 17 June 1997, the feast of the Holy Trinity, by Metropolitan Volodymyr Sabodan.

The cathedral publishes the journal "Troieshchyna Pravoslavna" since 1999 and runs a Sunday school with over 90 children aged 5 to 16. A vocal choir studio called "Yanholiatko" was founded in 2013 and now has more than 50 children. On the reverse of each icon in the main iconostasis, small plaques are engraved with the names of donors.

The cathedral stands on an artificial hill between the village of Troieshchyna and the Vyhurivshchyna-Troieshchyna housing estate. Divine Liturgy is served daily at 8:00 and evening services at 18:00, so visits outside those hours allow a quieter look at the interior. The bell tower is a separate four-tier structure near the main church.

The cathedral's central iconostasis, built in 1999, is seven tiers high, 15.2 m tall and 12.8 m wide, with 52.79 sq m of carving and 44 icons painted by masters from Pochaiv under Mykola Panchuk. Small engraved plaques on the back of each icon record the names of the donors who paid for it.
