The All Progressives Congress (APC) is a political party in Nigeria, formed on 6 February 2013 in anticipation of the 2015 elections. APC candidate Muhammadu Buhari won the presidential election by almost 2.6 million votes. Incumbent President Goodluck Jonathan conceded defeat on 31 March. This was the first time in Nigeria's political history that an opposition political party unseated a governing party in a general election and one in which power transferred peacefully from one political party to another. In addition, the APC won the majority of seats in the Senate and the House of Representatives in the 2015 elections, though it fell shy of winning a super-majority to override the ability of the opposition People's Democratic Party to block legislation.

The APC is generally considered to be a centre-left political party that favors controlled market economic policies, and a strong and active role for government regulation. A substantial number of its political leaders are followers of or politicians who subscribe to the social democratic political philosophy of Obafemi Awolowo and the socialist and anti-class views of Aminu Kano. Moreover, the majority of the APC's base of political support is in southwestern Nigeria and Northern Nigeria, which are dominated by the country's largest ethnic groups, the Yoruba and the Hausa-Fulani, respectively.
