Mario von Bucovich (16 February 1884 – 30 November 1947), also known as Marius von Bucovich, was an Austrian photographer. He was born at Pula in the Istrian region of the Austro-Hungarian Empire and held the title of Baron. His father, August, Freiherr von Bucovich (1852–1913), was a former Corvette Captain in the Austro-Hungarian navy and later an entrepreneur in the railroad concession sector. His mother was Greek.

He is believed to have been married four times.

The Berliner Morgenpost in 2009 described him as "one of the great unknown photographers of 20th Century European photography".
