Catastrophe Lake Boat Ramp is an unpaved launch site on Catastrophe Lake in the Kenora District of northwestern Ontario, listed among 38 boat ramps in the district.

The lake itself covers roughly 692 acres with about 12 miles of shoreline near the city of Kenora. Anglers report the launch as good but small, providing access to clear water with decent visibility.

The lake holds smallmouth bass and is known for extensive shallow areas and rocky shoals around its islands — the likely origin of the lake's name — making a functioning depth finder strongly advisable for navigation. The ramp is accessed via Minaki Highway.
