St. Stepanos or St. Yerordutyun Church was an Armenian church located in the northwestern part of the Ashagy Aylis village (Ordubad district) of the Nakhchivan Autonomous Republic of Azerbaijan.

[1][3] The church was a domed basilica; a cupola with eight-sided drum rested atop the flat roof, the plan included a five-sided apse on the exterior and a porch at the west end.

[2][1] The interior walls bore Armenian inscriptions and fragments of frescoes.

[1][2] St. Stepanos Church was still a standing monument in the late Soviet period (the 1980s).

[4] The church along with the adjacent St. Nshan Church was already completely erased by February 2000, as the investigation of the Caucasus Heritage Watch shows.
