2021 Chadian presidential election

Presidential elections were held in Chad on 11 April 2021. Incumbent Idriss Déby, who served five consecutive terms since seizing power in the 1990 coup d'état, was running for a sixth. Déby was described as an authoritarian by several international media sources, and as "strongly entrenched". During previous elections, he forbade the citizens of Chad from making posts online, and while Chad's total ban on social media use was lifted in 2019, restrictions continue to exist.

Provisional results released on April 19 showed that incumbent president Idriss Déby won reelection with 79% of the vote. However, on 20 April it was announced by the military that Déby had been killed in action while leading his country's troops in a battle against rebels calling themselves the Front for Change and Concord in Chad (FACT).

Following president Déby's death, a body called the Transitional Military Council – led by his son Mahamat Déby Itno, dissolved the government and the legislature, and proclaimed that it would be assuming power for a period of 18 months. Thereafter, a new presidential election would be held. Some political actors within Chad have labeled the installing of the transitional military government a "coup", as the constitutional provisions regarding the filling of a presidential vacancy were not followed. Namely, according to the constitution, the President of the National Assembly, Haroun Kabadi, should have been named Acting President after Déby's death, and an early election called within a period of no less than 45 and no more than 90 days from the time of the vacancy.
