Debre Libanos (Oromo: Dabra libanose; Amharic: ደብረ ሊባኖስ) is an Ethiopian Orthodox Tewahedo monastery in Ethiopia, lying northwest of Addis Ababa in the North Shewa Zone of the Oromia. It was founded in 1284 by Saint Tekle Haymanot as Debre Atsbo and was renamed as Debre Libanos in the 15th century. He meditated in a cave above the current monastery for 29 years.
