The prime minister of the Palestinian National Authority was the position of the official head of government of the Palestinian Authority government, which operated between 2003 and January 2013, when it was officially transformed into the State of Palestine. Some still refer to the position of the prime minister of the Gaza Strip as the prime minister of the Palestinian National Authority.

The Palestinian Authority, officially known as the Palestinian National Authority or the State of Palestine, is the Fatah-controlled government body that exercises partial civil control over West Bank areas "A" and "B" as a consequence of the 1993–1995 Oslo Accords. The Palestinian Authority controlled the Gaza Strip prior to the Palestinian elections of 2006 and the subsequent Gaza conflict between the Fatah and Hamas parties, when it lost control to Hamas; the PA continues to claim the Gaza Strip, although Hamas exercises de facto control. Since January 2013, the Palestinian Authority has used the name "State of Palestine" on official documents, although the United Nations continues to recognize the Palestinian Liberation Organization (PLO) as the "representative of the Palestinian people".
