Božo Petrović-Njegoš (Serbian Cyrillic: Божо Петровић-Његош; 1846−1929) was a Montenegrin vojvoda and politician.

After taking command of the Southern Army in the Montenegrin–Ottoman War of 1876–1878, he represented the Principality of Montenegro at the Congress of Berlin.

[4] However, in his memoirs, vojvoda Ilija Plamenac claims he was the de facto leader of the Southern Army as Božo was too young and inexperienced.

Božo was also the first president of the Montenegrin Great Court, after it was instituted in 1879, and he served there until 1882.

[2] Božo was jailed in December 1918 during the events that led to the creation of Yugoslavia.
