Boniface Alexandre (French pronunciation: [bɔnifas alɛksɑ̃dʁ]; 31 July 1936 – 4 August 2023) was a Haitian politician.

Trained as a lawyer, he worked for a law firm in Port-au-Prince for 25 years before being appointed to the Supreme Court in 1992.

[1] Alexandre, as the Chief Justice and therefore next in the presidential line of succession, assumed the office of president after the coup.

During Alexandre's acting presidency, Amnesty International reported "excessive use of force by police officers", extrajudicial executions, a lack of investigations into these, escalation of "unlawful killings and kidnappings by illegal armed groups", failure of officials to prevent and punish violence against women, dysfunctionality of the justice system, and forty or more people imprisoned without charge or trial.

[2] Alexandre left office on 14 May 2006, when René Préval, winner of the February 2006 presidential election, was sworn in as president.
