Tanburi Cemil Bey (1873, Istanbul – July 28, 1916, Istanbul) was an Ottoman tanbur, Turkish tambur, yaylı tambur, kemençe, and lavta virtuoso and composer, who has greatly contributed to the taksim (improvisation on a makam/maqam) genre in Ottoman classical music.

His son, Mesut Cemil Bey, was an equally renowned Turkish tambur virtuoso.

He began to play the tanbur quite early in his youth and by the age of 20, his renown had already spread among the tamburis of Istanbul.

His taksims and instrumental works he recorded on 78rpms with tanbur, kemençe, lavta, cello and yaylı tambur had considerable impact on generations of musicians following him.

The peşrevs and sazsemais he composed are pieces of great taste, requiring a developed performance technique.
