Beckwithia is an extinct genus of average to large size (5 centimetres or 2.0 inches to 12 centimetres or 4.7 inches), soft bodied artiopodan arthropods that lived during the late Middle and Upper Cambrian on the former paleocontinent Laurentia, in what are now Utah and Wisconsin. It has an inverted egg-shape, with a semi-circular head, 11 abdominal segments and a tail spine. It is a typical member of the group Aglaspidida.
