Giusto de' Menabuoi (c. 1320–1391) was an Italian painter of the early Renaissance. He was born in the Republic of Florence.
He was likely a pupil of Giotto but this is not definitive. De' Menabuoi was known for his use of colour and became a court painter for Da Carrara. His style was individual, with no links to the realism of his contemporaries Altichiero and Jacopo d'Avanzi, and he had no influence on the later development of Venetian painting.
