Phragmoteuthis is a genus of extinct coleoid cephalopod known from the late Triassic[1] to the lower Jurassic.

[2] Its soft tissue has been preserved; some specimens contain intact ink sacs.

[1] It had an internal phragmocone[1] and ten arms.

[3][4][5] Previously described species, P. conocauda and P. montefiorei got their own genus, Clarkeiteuthis.
