Johann Georg Ahle (June 1651 – 2 December 1706) was a German composer, organist, theorist, and Protestant church musician.
His father was Johann Rudolph Ahle, who supplied him with early musical training.
In 1671 his first book of arias was published, Neues Zehn Geistlicher Arien; all copies of this work are now lost, though a fragment survives.
In 1680 he was named poet laureate by Emperor Leopold I. Ahle's most well-known theoretical treatise was Johan Georg Ahlens musikalisches Gespräche (1695–1701), published in four volumes.
