Maria Wiłkomirska (3 April 1904 - 19 June 1995) was a Polish pianist.
Born in Moscow, Wiłkomirska was the daughter of violinist Alfred Wiłkomirski; her half-sister Wanda was a violinist, her half-brother Józef was a conductor, and her brother Kazimierz was a cellist.
From 1913 until 1917 she studied at the Moscow Conservatory under Nadezhda Briusova [ru] and Boleslav Yavorsky; in 1920 she moved to Warsaw where she became a pupil of Józef Turczyński.
She held positions as an instructor in Kalisz, Gdańsk, and Łódź, and in 1951 began teaching at the Chopin University of Music in Warsaw.
Wiłkomirska formed a piano trio with Wanda and Kazimierz and toured in Europe and Asia.
