The calculation of glueball masses based on Maldacena's duality between supergravity and Yang-Mills theory is reviewed. Earlier work for the spin zero sector is extended to the full J^PC multiplet for both QCD₃ and QCD₄. Contrary to expectation, the mass of the 0⁺⁺ state associated with the graviton is smaller than the mass of the ${\tilde 0}^{++}$ state from the dilaton. The strong coupling results for IIA supergravity, when restricted to the QCD₄ superselection sector, compare remarkably well with the ``known'' glueball spectrum of lattice QCD simulations.
