Fritz Wotruba (April 23, 1907 in Vienna - August 28, 1975 in Vienna) was an Austrian sculptor of Czecho-Hungarian descent. He was considered one of the most notable Austrian 20th century sculptors. In his work, he increasingly dissolves figurative components in favor of geometrical abstraction with the shape of the cube as the basic form.

His probably greatest work, on which he worked until his death, was the planning of the Church "of the Holy Trinity" in Mauer, Vienna, better known as Wotruba Church.

Many of his statues can be seen in public parks in Vienna. The Lying Adolescent is located in an exhibition in the Albertina. He escaped to Switzerland upon Hitler's ascent to power. A number of his sculptures were either lost or destroyed during the Second World War.

Wotruba is buried on the Zentralfriedhof (Central Cemetery) in Vienna, Austria.
