The blacknose shiner (Notropis heterolepis) is a species of fish belonging to the family Leuciscidae.

The blacknose shiner is a soft-rayed species up to 9.8 cm with toothless jaws, but gill arches that contain one or two rows of distinctive teeth.

[2] The blacknose shiner ranges from the Atlantic, Great Lakes, Hudson Bay, and Mississippi River north to Nova Scotia and Saskatchewan, south to Ohio, Illinois, south-central Missouri.

It is more prevalent in the northern sections of its range, and seems to be disappearing in the southern portions; it was last collected in Ohio in 1982.

[3] It lives typically in cool weedy creeks, small rivers, and lakes over sand.
