We have detected pulsations in time‐series photometry of the WZ Sge dwarf nova PQ Andromedae. The strongest peak in the power spectrum occurs at a period of 10.5 minutes. Similar periods have been observed in other WZ Sge systems and are attributed to ZZ Ceti–type nonradial pulsations. There is no indication in the photometry of an approximately 1.7 hr orbital period, as reported in previous spectroscopic observations.
