矮胖子（英语：Humpty Dumpty）是《鹅妈妈童谣》中的人物。

Humpty Dumpty is a character in an English nursery rhyme, probably originally a riddle and one of the best known in the English-speaking world. He is typically portrayed as an anthropomorphic egg, though he is not explicitly described so. The first recorded versions of the rhyme date from late eighteenth-century England and the tune from 1870 in James William Elliott's National Nursery Rhymes and Nursery Songs. Its origins are obscure and several theories have been advanced to suggest original meanings.
