Leopold Widlizka (also spelled Widliczka; November 14, 1870 – 1940) was an Austrian-American painter renowned for his portraits, landscapes, still lifes, and war scenes. Born in Vienna, he began his artistic education at the Graphische Lehr- und Versuchsanstalt under Joseph-Eugen Hörwarter. In October 1889, he attended the Academy of Fine Arts in Vienna as a guest student and became a regular student in 1891. He later continued his studies at the Academy in Munich, working under Nikolaus Gysis and drawing influence from artists like Franz von Lenbach and Hermann von Kaulbach.

Widlizka emigrated to the United States in 1922 and established himself as a painter in New York. He remained deeply connected to the Austrian art scene. He was still listed as a member of the Wiener Kunstgemeinschaft (Vienna Art Community) in 1924, indicating that he maintained ties with Austria even after settling in America.

His involvement as a war painter during World War I with the k.u.k. Kriegspressequartier (Imperial and Royal War Press Headquarters) is a fascinating aspect of his career. His war-related works, including one of his notable works, Familienschicksal (1918), an oil painting housed in the Heeresgeschichtliches Museum in Vienna, captures the human impact of war, a subject that was less prominent in his later American paintings.
