Parafusulina is a genus of foraminifera included in the fusulinacean family Schwagerinidae that were extant during the Permian.

The shell, or test, of Parafusulina is elongate, up to 65 mm in length, fusiform to subcylindrical in shape, tapering slightly to the bluntly rounded poles.

The proloculus is large, followed by seven to nine gradually enlarging volutions, coiled around a straight to irregular axis.

Walls (spirotheca) are composed of an outer tectum and inner alveolar keriotheca and are thin in relation to the size of the test.

Tunnels, single in any individual, are low and well defined but are without bordering chomata.
