Hadronic parity violation (PV) allows for fine tests of the Standard Model. In this talk, I review the efforts to tackle this problem from chiral effective field theories and lattice QCD. A particular focus is set on the weak pion-nucleon coupling constant, which dominates the long- range part of hadronic PV, but is purely known to date. A concise program to tackle hadronic PV using few-nucleon reactions is also laid out.
