Alesso or Alessio Baldovinetti (14 October 1425 – 29 August 1499) was an Italian early Renaissance painter.
Baldovinetti was born in Florence to a rich noble family. In 1448 he was registered as a member of the Guild of St. Luke: "Alesso di Baldovinetti, dipintore."
His finest works include a damaged but still enchanting fresco of the Nativity (1460-62) in the forecourt of the SS. Annunziata, Florence, a Madonna and Child (c. 1460) in the Louvre, Paris, and an Annunciation (c. 1460) in the Uffizi, Florence. They show his remarkable sensitivity to light and landscape and his engaging blend of naivety and sophistication. In his History of Italian Renaissance Art (1970), Frederick Hartt writes that Baldovinetti was 'the finest painter in Florence ' in the 1460s, and considers him 'a very gifted master who somehow never quite seemed to fulfil his great initial promise'.
