Anton Paul Stadler was an Austrian clarinet and basset horn player for whom Wolfgang Amadeus Mozart wrote, amongst others, both his Clarinet Quintet and Clarinet Concerto. Stadler's name is inextricably linked to Mozart's compositions for these two instruments.

Wolfgang Amadeus Mozart's Clarinet Concerto in A major, K. 622, was completed in October 1791 for the clarinettist Anton Stadler. It consists of three movements, in a fast–slow–fast succession.
