Clemens Holzmeister (27 March 1886 – 12 June 1983) was a prominent Austrian architect and stage designer of the early twentieth century. The Austrian Academy of Fine Arts listed his life's work as containing 673 projects. He was the father of Judith Holzmeister.

Holzmeister was born in the village of Fulpmes in the Tyrol state of Austria. He and Judith Bridarolli married in 1913 in Innsbruck. In 1914 His son Guido was born in Vienna. He attended the Vienna University of Technology and earned a doctorate in architecture in 1919. His daughter Judith Holzmeister was born in Innsbruck in 1920. After submitting a prize-winning design, he became the Head of the Architecture Department of Austria's Academy of Fine Arts in 1924. In 1926 he oversaw the remodelling of the Festival Theatre in Salzburg, then spent several years erecting government buildings in Ankara, Turkey.

In 1931 Holzmeister became the Director of the Austrian Academy of Fine Arts. Besides building projects in Austria, Germany and Turkey, he remained the Director of the Academy until being removed from this post during the Anschluss by the new German government in 1938. Although his offices, journals and papers were seized by the Nazis, he had the good luck to be in Turkey on another commission at the time; during which he designed the former Turkish Parliament building (1938) as well as numerous other state buildings. He remained in Turkey until 1954, then returned to Austria, where his 1950s commissions include the Großes Festspielhaus.

His body of work includes a large number of public and semi-public buildings and churches. He developed a new interpretation of local building traditions between simplicity and expressiveness. He also built monuments and scenery.

Holzmeister repeatedly worked as a stage designer beginning in the 1930s in collaboration with Max Reinhardt for whom he created the Faust-City for the Salzburg Festival. In the 1950s Holzmeister returned to stage design and again worked for the Salzburg Festival (Don Giovanni) as well as the Vienna State Opera (Fidelio, 1955, for the opening of the renovated State Opera) and the Burgtheater. Holzmeister's stage designs always respected the requirements of stage productions but never concealed the architectonic background of their creator.

He is buried in St. Peter's Cemetery in Salzburg.
