The National Convention Party (NCP) is a centre-left political party in the Gambia. It was the main opposition party between 1975 and 1994. It was originally founded on 7 September 1975 when it first launched at Busumbala by former vice-president Sheriff Mustapha Dibba two weeks after his expulsion from the People's Progressive Party (PPP).
When the NCP was first established, then-incumbent president Dawda Jawara of the PPP predicted that the party would not last more than three months. Sheriff Dibba ran as the NCP presidential candidate in every election from 1982 to 1992, each time finishing second to Jawara.
The NCP initially welcomed the 1994 coup but was banned from participating in elections in August that year. Prior to the 1992 elections, the party faced a series of setbacks as many of its leaders rejoined the PPP. Its candidate at the 2001 presidential election, Sheriff Dibba, came fourth with 3.77% of the popular vote. The NCP was part of Coalition 2016 for the 2016 presidential election, where it endorsed opposition candidate Adama Barrow who would eventually go on to win the election.
