The Cello Sonata No. 3 in A major, Op. 69, is the third of five cello sonatas by Ludwig van Beethoven. He composed it in 1807–08, during his productive middle period. It was first performed in 1809 by cellist Nikolaus Kraft and pianist Dorothea von Ertmann, a student of Beethoven. Published by Breitkopf & Härtel the same year, it was dedicated to Freiherr Ignaz von Gleichenstein, Beethoven's friend and an amateur cellist. The sonata was successful with audiences from the beginning.
