We have obtained time series optical spectra of the cataclysmic variable PQ And in quiescence. The spectra show a white dwarf continuum with narrow Balmer emission superimposed over strong Balmer absorption. The emission lines have blue and red components whose strength changes with time. An analysis of the Hα emission line implies a short orbital period below the period gap. Given its lack of accretion disk features, its large and infrequent outbursts, and an orbital period below the period gap, PQ And is probably a low accretion rate object similar to WZ Sge. In addition, white dwarf model fits imply that PQ And is an excellent ZZ Cet candidate.
