Top 10 longest serving Presidents in Africa (2026)
Africa has witnessed numerous leaders whose time in power has stretched across decades. Among them, Equatorial Guinea’s President, Teodoro Obiang, stands out as both the longest-serving leader on the continent and, indeed, globally. Close behind him is Cameroon’s President, Paul Biya, who is currently in his seventh consecutive term.
Such prolonged tenures are often attributed to a mixture of constitutional amendments, disputed electoral processes, and the marginalisation of political opposition. While their longevity in office is notable, many of these leaders have also faced persistent criticism over allegations of corruption, human rights violations, and ineffective governance.
What follows is a restructured overview of Africa’s current heads of state, ranked according to the length of their uninterrupted time in office.
