Wolfgang Amadeus Mozart's concertos for piano and orchestra are numbered from 1 to 27. The first four numbered concertos and three unnumbered concertos are early works that are arrangements of keyboard sonatas by various contemporary composers. Concertos 7 and 10 are compositions for three and two pianos respectively. The remaining twenty-one are original compositions for solo piano and orchestra. These works, many of which Mozart composed for himself to play in the Vienna concert series of 1784–86, held special importance for him.

Wolfgang Amadeus Mozart was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition resulted in more than 800 works representing virtually every Western classical genre of his time. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoire. Mozart is widely regarded as being one of the greatest composers in the history of Western music, with his music admired for its "melodic beauty, its formal elegance and its richness of harmony and texture".
