The New Mon State Party (NMSP) (Burmese: မွန်ပြည်သစ်ပါတီ) is an opposition party in Myanmar. Its armed wing, the Mon National Liberation Army (MNLA), has fought the government of Myanmar since 1949, but under different names. The NMSP has attempted many times unsuccessfully to push for constitutional and political reforms through the government sponsored National Convention. NMSP had signed a ceasefire pact with the government in 1995 but the pact turned invalid when the party refused to accept to transform itself into a border guard unit.

Current chair-person is Nai Htaw Mon.
