The snubnose blacksmelt (Bathylagoides wesethi) is a species of ray-finned fish in the deep-sea smelt family Bathylagidae.

The snubnose blacksmelt is a small, laterally-compressed, elongated fish, deepest near the head and tapering towards the tail.

The snout is rounded and has a terminal, diagonal mouth; its length is about half the diameter of the rather large eye.

The dorsal fin has ten to fourteen soft rays and is set well back on the body.

[3] The snubnose blacksmelt is found in deep water in the Pacific Ocean off the western coast of North America.
