The Nigerian presidential line of succession is the set order of Nigerian government officials who may become or act as president upon the incapacity, death, resignation, or removal from office (by impeachment and subsequent disqualification) of a sitting president or a president-elect.
A general election must be called before the window elapses.
In May 2010, the death of President Umaru Musa Yar'Adua triggered the succession order, leading to the succession of his Vice as President of the Federal Republic of Nigeria.
The current presidential line of succession to the office of the president of Nigeria is specified by the 1999 Constitution.
Contrary to popular belief, the presidential line of succession does not include the speaker of the House of Representatives and the chief justice.
