Syllomus is an extinct genus of sea turtle from the Miocene-age deposits in the US Eastern Seaboard and Egypt.


Two species are known, Syllomus aegyptiacus (Lydekker, 1889) and S. crispatus Cope, 1896.[1][2][3][4] Lapparent de Broin (2001) considers Trachyaspis a possible senior synonym of Syllomus.[5]
