Buhari ran in the 2015 presidential election as a candidate of the All Progressives Congress party.
His platform was built around his image as a staunch anti-corruption fighter and his incorruptible and honest reputation, but he said he would not probe past corrupt leaders and would give officials who stole in the past amnesty if they repented.

In the runup to the 2015 election, Jonathan's campaign asked that Buhari be disqualified from the election, claiming that he was in breach of the Constitution.
According to the fundamental document, in order to qualify for election to the office of the president, a person must be "educated up to at least School certificate level or its equivalent".
Buhari failed to submit any such evidence, claiming that he lost the original copies of his diplomas when his house was raided following his overthrow from power in 1985.

In May 2014, in the wake of the Chibok schoolgirls kidnapping, Buhari strongly denounced the Boko Haram insurgency.
He "urged Nigerians to put aside religion, politics and all other divisions to crush the insurgency he said is fanned by mindless bigots masquerading as Muslims".
In July 2014, Buhari escaped a bomb attack on his life by Boko Haram in Kaduna, 82 people were killed.
In December 2014, Buhari pledged to enhance security in Nigeria if elected president.
After this announcement, Buhari's approval ratings skyrocketed, largely due to Jonathan's apparent inability to fight Boko Haram.
Buhari made internal security and wiping out the militant group one of the key pillars of his campaign.
In January 2015, the insurgent group "The Movement for the Emancipation of the Niger Delta" (MEND) endorsed Buhari.

Buhari's campaign was briefly advised by former Obama campaign manager David Axelrod and his AKPD consultancy.
In February 2015, former Nigerian President Olusegun Obasanjo quit the ruling PDP party and endorsed Buhari.

On 31 March, Jonathan called Buhari to concede and congratulate him on his election as president.
Buhari was sworn in on 29 May 2015 in a ceremony attended by at least 23 heads of state and government.
