"Thymallus yaluensis" is a species of freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes. The species has been reported in Korea, Siberia, the Alps in Europe, and the northern Mississippi River drainage in North America.

"T. yaluensis" reaches a maximum recorded length of 20 cm (8 in), the smallest of the "Thymallus" species.

There is some confusion about the classification of "T. yaluensis." Very similar in form to the Arctic grayling ("T. arcticus"), it may be identical to the Amur grayling subspecies ("T. arcticus grubii"); it has also been classified as its own subspecies, "T. arcticus yaluensis." The spelling "T. jaluensis," while invalid, is encountered.

The specific epithet, "yaluensis," derives from the name of the Yalu River on the North Korean–Chinese border.
