Paul Arma (Hungarian: Arma Pál, aka Amrusz Pál; né Weisshaus Imre; 22 November 1905 – 28 November 1987) was a Hungarian-French pianist, composer, and ethnomusicologist.

Arma was born in Budapest in 1905. He studied under Béla Bartók from 1920 to 1924 at the Franz Liszt Academy of Music, after which time he toured Europe and America giving concerts and piano recitals. Béla Bartók influenced Arma in his love for folksong and collection. He left Hungary in 1930, eventually settling in Paris in 1933, where he became the piano soloist with Radio Paris. His music is generally characterised by modernist tendencies, although his varied output includes folk song arrangements, film music, popular and patriotic songs, in addition to solo, chamber, orchestral and electronic music.

Arma died in Paris in 1987.
