Interim president: Jocelerme Privert
Jocelerme Privert was named as interim president by parliament in February 2016 to fill a power vacuum caused by the disputed result of the first round of voting to elect a new president in October.
He promised that his mandate, limited to 120 days, would focus on restoring national security, restoring the rule of law and completing the stalled electoral process."
The election was won by Jovenel Moise, but opposition challenger Jude Celestin accused the electoral authorities of favouring Mr Moise, and threatened to pull out of the run-off, which was repeatedly postponed, at times amid unrest throughout the country.
A special commission has recommended a re-run of the October election, saying it had been marred by the registration of "zombie voters".
Mr Privert replaced Michel Martelly, a famous Haitian musician with no history of political office who stormed to victory in the 2011 presidential election.
President Martelly ran an unusually slick campaign, enlisting advisers to project a more serious image than that of the flamboyant musician who made his name playing compas dance music in the 1980s.
Having steered clear during the Duvalier regime in the 1980s, Mr Martelly became politically active in opposition to President Jean-Bertrand Aristide, Haiti's first freely-elected president in 1991.
His shows were patronised by some leading figures in the violent military dictatorship that ousted Mr Aristide later that year, which is when he acquired the nickname of "Sweet Micky".
After Mr Aristide's return to Haiti in 1994 Mr Martelly largely concentrated on his musical career.
Mr Martelly's pledge to rebuild a country still reeling from the after-effects of the devastating January 2010 earthquake appealed to the poor and unemployed, and he became especially popular with younger voters.
However, he courted controversy in 2012 by advocating the re-establishment of Haiti's army, which was scrapped in the 1990s because of its history of coups and violence.
He faced protests in 2012 and 2014 against enduring corruption and his failure to alleviate poverty.
Prime Minister: Jean-Charles Enex
A long-serving adviser to a number of presidents, Mr Enex became prime minister in March 2016 at the head of an interim cabinet to oversee the transition of power after the departure from office of President Martelly.
