Franz Xaver Biebl (1 September 1906 – 2 October 2001) was a German composer of classical music. Most of his compositions were for choral ensembles.

Biebl was born in Pursruck, now part of Freudenberg, Bavaria, in 1906. He studied composition at the Musikhochschule in Munich. Biebl served as choir director at the Catholic church of St Maria in München-Thalkirchen from 1932 until 1939, and as an assistant professor of choral music at the Mozarteum, an academy of music in Salzburg, Austria, beginning in 1939, where he taught voice and music theory.

Biebl was drafted into the military beginning in 1943 during World War II. He was a prisoner of war from 1944 to 1946, being detained at Fort Custer in Battle Creek, Michigan. After the war, he moved from Austria to Fürstenfeldbruck, Germany, where he served as director of the town chorus.
