Lazar Tešanović (Serbian Cyrillic: Лазар Тешановић) was a Serbian schoolteacher and military officer.
He was a reserve lieutenant of Royal Yugoslav Army and, later, the Chetniks military officer during World War II.
During the War, Tešanović founded the Obilić Detachment which operated between two rivers, Vrbas and Vrbanja, and south to mount Vlašić.
[1] Detachment took a main part in the Lipovac ambush on the Partisans Company led by Mladen Stojanović, who was badly wounded in the fight.
On 23 May 1942, Tešanović entered into an agreement with the Independent State of Croatia, asking arms and ammunition to fight against the Partisans.
