The String Quartet No. 13 in B♭ major, Op. 130, by Ludwig van Beethoven was completed in November 1826. The number traditionally assigned to it is based on the order of its publication; it is actually Beethoven's 14th quartet in order of composition. It was premiered in March 1826 by the Schuppanzigh Quartet and dedicated to Nikolai Galitzin on its publication in 1827.

The Schuppanzigh Quartet was a string quartet formed in Vienna in the 1790s by the violinist Ignaz Schuppanzigh. It continued, with breaks and changes of membership, for many years. Schuppanzigh was a close friend and admirer of Ludwig van Beethoven, and the quartet gave the first performances of many of Beethoven's string quartets.
