We describe actions that correspond to the interaction of the super-Virasor
o algebra with supergravitons. These new field theories introduce a superfi
eld that corresponds to dual elements of the super-Virasoro algebra. Such e
lements already appear as background fields in the geometric action associa
ted with two-dimensional Polyakov gravity. The actions derived here supply
dynamics to these otherwise background fields. We are also able to extend t
he definition of these field theories to higher dimensions. We explicitly e
xhibit the 2-, 3- and 4-dimensional cases. Remarkably, the fundamental prep
otentials describing these dual elements of the super-Virasoro algebra, in
each model, agrees with the known prepotentials of the corresponding superg
ravity theory. These theories might be important in the quantization of the
super-Virasoro group, supergravity and in AdS and super AdS gravity. (C) 2
