Wojciech Żywny (Czech: Vojtěch Živný; 13 May 1756 – 21 February 1842) was a Czech-born Polish pianist, violinist, teacher and composer.

As a youth, during the reign of Stanisław August Poniatowski, he moved to Poland to become the music tutor to the children of Princess Sapieha.

Żywny instilled in Chopin a lasting love of Bach, Haydn, Clementi and Mozart while avoiding contemporary composers like Beethoven and Weber.

In 1821, eleven-year-old Chopin dedicated a Polonaise in A-flat major to Żywny as a name-day gift.

Żywny wrote many pieces for piano, and violin, as well as orchestral works, few of which are known or published today.
