Vjera Petrović-Njegoš, Princess of Montenegro^[a] (Serbian Cyrillic: Вјера Петровић-Његош; 22 February 1887 – 31 October 1927) was a member of the House of Petrović-Njegoš, ruling family of the Kingdom of Montenegro.

Vjera was born as the ninth daughter and eleventh (of twelve) child of Nicholas I of Montenegro and his wife, Milena of Montenegro.^[1]

Vjera and her sister Princess Xenia were not educated at the Smolny Institute in Russia like her eldest sisters had been, but educated at home. She was described as pretty and elegant but more sensitive and timid, and not as energetic or strong-willed, like her elders sisters.^[2]

She was interested in painting, but is foremost remembered because of the effort she made helping the injured victims of an explosion in the harbor of Bar, for which she was awarded a medal.^[3] She left Montenegro when her father was deposed in 1918 and settled with her parents and her sister Xenia in France. She participated in humanitarian work in France as well. As young girls, Vjera's father had high hopes that she and her elder sister Xenia would marry members of the Russian Imperial family.^[4] Although eligible, she decided to never marry.

She died in France. She was buried with her parents and sister in San Remo, but like them, her remains were reburied in Cetinje in 1989.
