Surp Khach Church (Armenian: Սուրբ Խաչ [suɾpʰ χɑtʃʰ], Russian: Церковь Святого Креста, Holy Cross Church) is an 18th-century Armenian church in Nor Nakhichevan. It is the oldest surviving monument in the borders of Rostov-on-Don.
The church was built in 1786–1792. In 1972, it was turned into a museum of Russian-Armenian friendship, but was reopened as an Armenian Apostolic Church in 2000.
The church is situated in the modern-day Voroshilovsky (North) rayon, on a high hill near the river. Several famous Armenian people like Harutyun Alamdaryan, Raphael Patkanian and Mikael Nalbandian are buried near the church.
