We observed Moir\'e fringes in spatial quantum correlations between twin photons generated by parametric down-conversion. Spatially periodic structures were nonlocally superposed giving rise to beat frequencies typical of Moir\'e patterns. This result brings interesting perspectives regarding metrological applications of such a quantum optical setup.
