Kornél Ábrányi (Hungarian pronunciation: [ˈkorneːl ˈaːbraːɲi]; 15 October 1822 – 20 December 1903) was a Hungarian pianist, music writer and theorist, and composer.

A pupil of Frédéric Chopin, and a close friend of Franz Liszt, whose music he championed, Ábrányi chiefly wrote music for piano, but also composed chamber music, choral works, and lieder.

He began teaching at the Franz Liszt Academy of Music at its founding in 1875 and became its secretary.

[1] Ábrányi died in Budapest, aged 81.

His grandson was the composer Emil Ábrányi.
