The Piano Concerto No. 16 in D major, K. 451, is a concertante work for piano, or pianoforte, and orchestra by Wolfgang Amadeus Mozart. Mozart composed the concerto for performance at a series of concerts at the Vienna venues of the Trattnerhof and the Burgtheater in the first quarter of 1784, where he was himself the soloist. Mozart noted this concerto as complete on 22 March 1784 in his catalog, and performed the work later that month. Cliff Eisen has postulated that this performance was on 31 March 1784.
