Hantkeninacea are globigerid forams with planispiral or enrolled biserial tests, found in marine sediments of Paleocene to Miocene age, in which chambers vary from globular to elongate and the primary aperture is equatorial in position. Includes three families, the Globanomalinidae, Hankeninidae, and Cassigerinellidae.

Members of the Hantkeninacea were included in the family Hantkenindae, established by Cushman, 1927, as defined in the Treatise, part C, 1964, which is accordingly included in the Globigerinacea, a superfamily in the foraminiferal suborder, Rotaliina.
