Stylinodon ("tooth with pilar-like fibers") is an extinct genus of taeniodonts from extinct tribe Stylinodontini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from early to middle Eocene.

With a weight between 54.9 kg (121 lb) and 109 kg (240 lb), and length of 1.30 m (4 ft 3 in), it had similar size to a pig. The skull suggests it had a blunt face, and a very short snout. Its canines had developed into huge, incisor-like root-less teeth. Stylinodon's molars were covered in enamel and continued growing throughout its life. Most likely, it fed on rough roots and tubers.
