Ivan Kushchnyk Tower (Ukrainian: Вежа Іоанна Кущника, Russian: Башня Иоанна Кущника) is a defensive tower with a church, part of the Kyiv Pechersk Lavra fortifications, Kyiv, Ukraine.

It is built from brick, covered in white plaster and decorated with profiled cornice.

Ceilings of the ground and the first floors were originally wooden, but were later replaced by stone, thus increasing tower fire resistance.

The tower had a gallery on the monastery side, supported by wooden consoles connected to the general system of defensive walls.

During that renovation the lower walls and vaults of the tower were strengthened, the windows of the top floor and tier under cupola were reopened, and the cross re-gilded.
