Parity violation provides a new probe of fundamental physics in the primordial Universe. Recent hints of parity-odd signals in large-scale structure motivate a careful connection between primordial parity-violating non-Gaussianity and late-time observables. We derive the parity-odd matter trispectrum at one-loop order, including the effects of nonlinear gravitational evolution. We then extend the calculation to biased tracers and obtain the halo trispectrum in the presence of primordial parity-violating non-Gaussianity. Our results provide a theoretical framework for searching for primordial parity violation in galaxy and halo four-point statistics.
