St. Grigor Church was an Armenian church located in the village of Kulus (Shahbuz District) of the Nakhchivan Autonomous Republic of Azerbaijan.

[2][3] It was a basilica-style church consisting of two aisles and a nave, an apse, two vestries, and a hall.

Its distinctive roof, with a curved form that gives the impression of a dome, is characteristic of the Persian-Armenian community of Isfahan.

[2][3] The church was a standing monument in the late Soviet period.

[1] The church was destroyed at some point between 1997 and November 11, 2009, as documented by Caucasus Heritage Watch.
