Burundi Workers' Party

Burundi Workers' Party or UBU (French: Parti des travailleurs du Burundi; Kirundi: Umugambwe wa'Bakozi Uburundi) was a clandestine communist party in Burundi. Its primary constituency was the large Burundian refugee population situated in neighboring Rwanda. Founded in August 1979, one of its most prominent leaders was the ethnic Hutu intellectual Melchior Ndadaye, who became the first democratically elected president of Burundi in 1993.

When UBU was disbanded, followers of Ndadaye regrouped into the Front for Democracy in Burundi (FRODÉBU).
