Harpagofututor is an extinct genus of eel-like cartilaginous fish from the Early Carboniferous (Mississippian) Bear Gulch Limestone of Montana in North America.

The fish was discovered in the 1980s in Montana's Bear Gulch area by Adelphi University palaeontologist Richard Lund, who has been exploring the limestone formations of the region since 1969.

[3] The genus is placed in the family Chondrenchelyidae, which are suggested to be members of Holocephali, with their closest living relatives being chimaeras.

The mouth has pairs of tooth plates in the upper and lower jaws, comparable to those of living chimaeras, which were triangular in shape.

[3] Harpagofututor is suggested to have given live birth, with newborn juveniles being proportionally large and morphologically nearly identical to adults.
