Multiple superdeformed rotational bands have been identified in a nucleus for the first time. Cascades of 14, 13, and 11 transitions have been assigned to three bands in {sup 153}Dy. Despite the small intensities, it has been possible to follow the decay of these bands from an angular frequency of 0.7 down to 0.4 MeV/{h bar}. In all three cases, the dynamic moment of inertia {ital I}{sup (2)} is nearly constant. Assignments to high-{ital N} intruder orbitals are suggested through comparison of these values of {ital I}{sup (2)} with theoretical calculations based on the cranked shell model.
