John W. Bischoff (27 November 1850 in Chicago – May 30, 1909 in Washington, DC) was a blind musician and composer.

Blind from age two, Bischoff went on to become a noted organist, compiler of musical collections, and composer. He was the principal organist and choir director at the first Congregational Church in Washington from 1874 until his death in 1909.

Bischoff lost his sight at about two years of age, and attended the Wisconsin School for the Blind. Later he studied singing with Ludden and Bassini in Chicago and studied organ under Creswald. In 1875 he moved to Washington and became the principal organist and choir director at First Congregational Church, posts he held until his death.

He was a great composer and compiler of music, and was considered one of the greatest composers and greatest organists of the country. His compilations included a significant number of his own works, including Crystal Songs (1877, with the help of Dr. Otis Presbrey), Gospel Bells (1883, with Jeremiah Rankin), God Be With You (1880), and Not Half Has Been Told (1877). Some of his works were published by Arthur P. Schmidt. Much of his composing was done during the summer when he would visit his cottage on Wisconsin's Lake Winnebago.

Bischoff married Mary Jane Vandergrift, daughter of Howard Vandergrift, in Mount Carroll, Illinois in about 1870. They had met in Fond du Lac, Wisconsin, where Bischoff lived at the time. They had two children, a son John E. and a daughter Lucile. He divorced in 1895, and remarried to Elsie Bond Bischoff.

Bischoff died the morning of May 30, 1909 of heart disease after three weeks of illness. He was interred in Rock Creek Cemetery.
