Johann Christoph Oley (1738-1789) was a German organist and composer. There is some evidence that he studied with J.S. Bach for a short time in 1749, but none connecting him with the Thomasschule. In 1755 he became organist of the church in Bernburg (Saxony-Anhalt), but moved to the church of St Stephan in neighbouring Aschersleben in 1762 because of its superior organ.
