The Piano Sonata No. 11 in A major, K. 331 / 300i, by Wolfgang Amadeus Mozart is a piano sonata in three movements. It is uncertain where and when Mozart composed the sonata; however, Vienna or Salzburg around 1783 is currently thought to be most likely (Paris and dates as far back as 1778 have also been suggested).
The sonata was published by Artaria in 1784, alongside Nos. 10 and 12 (K. 330 and K. 332).
沃尔夫冈·阿马德乌斯·莫扎特（Wolfgang Amadeus Mozart）的第11号钢琴奏鸣曲，K。331 / 300i，是三首乐章中的钢琴奏鸣曲。 不确定莫扎特何时何地创作奏鸣曲; 然而，目前认为维也纳或萨尔茨堡大约在1783年左右（巴黎和日期可以追溯到1778年）。
奏鸣曲于1784年由Artaria出版，与第10和第12期（K.330和K.332）一起出版。
