Mosor je planina u Dalmaciji. Proteže se uz more, na potezu od Splita do Omiša.
Podrijetlo naziva Mosor ima nekoliko tumačenja:
od fra. mons d'or = zlatna planina;
od ilirskih riječi mol = brdo i sor = izvor;
od lat. naziva Massarum.
Najviši vrh je Veliki Kabal (1339 m), a jedan od posjećenijih vrhova je Vickov stup (1325 m). Na vrhu Sveti Jure (1319 m) nalazi se istoimena rimokatolička kapelica.
