Pathius is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and the Arabian Peninsula.
The genus was originally named Taphius by Martin Jacoby in 1897; however, this name was preoccupied by Taphius <small>Adams, 1855</small> (a genus in Mollusca, currently a synonym of Biomphalaria <small>Preston, 1910</small>) and Taphius <small>Rafinesque, 1815</small> (a nomen nudum genus in Crustacea), so it was renamed to Pathius by N. A. Aslam in 1968.
