A presidential referendum was held in Haiti on 30 April 1961 alongside parliamentary elections. Voters were asked whether President François Duvalier should remain in office for a further six years. The official count was 1,320,748 votes in favor of Duvalier and none against. The New York Times wrote that "Latin America has witnessed many fraudulent elections throughout its history but none has been more outrageous than the one which has just taken place in Haiti."
