President Ndadaye's Day is an annual national holiday in the Republic of Burundi, celebrated every October 21. It's a day dedicated to commemorating the death of Melchior Ndadaye, the country's first democratically elected President and the first Hutu to become president. His election marked a significant turn in Burundian history as it signified the end of the longstanding Tutsi rule, giving way to more political balance.

On President Ndadaye's Day, the citizens of Burundi engage in various activities and events dedicated to honoring the legacy of their late president. From public speeches by government officials and dignitaries to reflections on the event surrounding Ndadaye's death, President Ndadaye's Day is an opportunity for the people of Burundi to remember their history. Vigils, prayers, and tributes common place on this day.

Melchior Ndadaye's presidency, although short-lived, marked the start of a democratic era in Burundi. His assassination in 1993 led to widespread civil unrest and violence, which would later be known as the Burundian Civil War. On President Ndadaye's Day, the nation remembers not only Ndadaye, but also reflects on the period of national development that began with his presidency. It is a day of national mourning, remembrance, and ultimately, unity within Burundi.
