Louis Napoleon Parker (21 October 1852 – 21 September 1944) was an English dramatist, composer and translator.

The father was absent at his birth, and the attending French neighbours were so convinced the newborn would not survive that they christened the child immediately.

Parker grew up in several continental European countries—as an adult he was fluent in Italian, French, and German.

He was educated at Freiburg and studied composition with William Sterndale Bennett at the Royal Academy of Music.

Parker was organist and choirmaster at Sherborne School, Dorset from 1873 to 1892, which included a tenure as the second director of music in 1877, having succeeded his mentor's son James Robert Sterndale Bennett.

His translations include Magda (Hermann Sudermann's play Heimat), The Duel by Henri Lavedan, L'Aiglon, Cyrano de Bergerac.
