The Rotaliporacea is a superfamily of globigerinid foraminifera known from the Cretaceous characterized by trochospirally coiled test with primary apertures extraumbilical-umbilical that have a relatively prominent lip, and which may have secondary apertures along the sutures on the umbilical side that open into the posterior margins of the chambers.

The Rotaliporacea is essentially the Rotaliporidae of Loeblich and Tappan, 1964, elevated in rank in concert with the elevation of foraminifera from Order to Class.
