Wolfgang Amadeus Mozart's Oboe Concerto in C major, K. 314 (271k), was composed in the spring or summer of 1777, for the oboist Giuseppe Ferlendis (1755–1802) from Bergamo.

The oboe concerto was rediscovered by Bernhard Paumgartner in 1920, who found a handwritten set of parts in the Salzburg Mozarteum archives, and recognized the similarity with the flute concerto in D.[2][1] Alfred Einstein, editor of the third edition of the Köchel catalogue (1937), noted that both a D major and a C major copy of the K. 314 concerto existed in the library of the Gesellschaft der Musikfreunde in Vienna.

From this and also from Paumgartner's discovery, Einstein concluded that the concerto was originally for oboe.

The priority of the oboe version is supported by Mozart's letters, as well as various evidence from the music itself.
