Hailu Yimenu (died 1991) was an Ethiopian politician who was the acting prime minister of the People's Democratic Republic of Ethiopia from November 8, 1989 until 26 April 1991.

In May 1991, after hearing of Mengistu Haile Mariam's fall from power, he fled to the Italian embassy in Addis Ababa, along with Lieutenant General Tesfaye Gebre Kidan, Foreign Minister Berhanu Bayeh, and Chief of General Staff Addis Tedla. He was succeeded by Tesfaye Dinka.

While the other three remained at the embassy for years, Hailu killed himself shortly after fleeing to the embassy in 1991.^[1]

Following the death of General Tesfaye thirteen years later on 2 June 2004, rumors began to circulate caused by the embassy's lack of detail on the death of both General Tesfaye and Hailu's earlier suicide. The Ethiopian government demanded Italian records on the incidents during that month.
