Open Hostility is the seventh studio album by Canadian speed/thrash metal band Razor, released in 1991 by Fringe Product.

Drummer Rob Mills was unable to participate on the album due to injuries sustained in an accident, so his parts were performed by guitarist Dave Carlo using a drum machine.

Mills later returned for the filming of the "Sucker for Punishment" music video.

Open Hostility is dedicated to the memory of Ray “Black Metal” Wallace.
