Moritz (Maurice) Moszkowski (23 August 1854 – 4 March 1925) was a German composer, pianist, and teacher of Polish descent. Ignacy Paderewski said, "After Chopin, Moszkowski best understands how to write for the piano". Although little known today, Moszkowski was well-respected and popular during the late nineteenth century.

His music is brilliant, but has also been described as "devoid of the masculine and the feminine". He wrote over two hundred small-scale piano pieces, which brought him much popularity – notably his set of Spanish Dances, Op. 12, for piano duet (later arranged for solo piano, and for orchestra ). His early Serenade, Op. 15, was world-famous and appeared in many guises, including the song Liebe, kleine Nachtigall. Today he is probably best known for his fifteen Études de Virtuosité, Op. 72, which have been performed by virtuoso pianists such as Vladimir Horowitz and Marc-André Hamelin. Surprisingly, their first complete recording was not until 1970 (by Ilana Vered). Many of his small but brilliant piano pieces, such as Étincelles (Sparks), are used as encore performances at the end of classical concerts.
He also wrote larger scale works including the Piano Concerto in E major, Op. 59 (1898), the Violin Concerto in C major, Op. 30, three orchestral suites (Opp. 39, 47, 79), and a symphonic poem Jeanne d'Arc, Op. 19.
He wrote the opera Boabdil der letzte Maurenkönig, Op. 49, on the historical theme of the capture of Granada. It was premiered at the Berlin Court Opera on 21 April 1892, and appeared in Prague and New York the following year. It did not stay in the repertoire, but its ballet music was very popular for a number of years. He wrote a three-act ballet Laurin in 1896.
