Franz Lehrndorfer (10 August 1928 – 10 January 2013) was a German organist, composer, and pedagogue.
He received his first music lessons from his father, a choir director and musicologist and began to play the organ at age nine.
From 1948 until 1951, Lehrndorfer studied sacred music in Munich and obtained a master class diploma in organ performance in 1952.
As a performer, he often included music by Johann Sebastian Bach and Max Reger, as well as works by contemporary composers, such as Karl Höller and Harald Genzmer, in his programs.
In 2001, he played the premiere of Genzmer's Concerto for organ, which he subsequently edited for Schott Music.
