Robert Whittington (also spelt Wittinton, Whitynton, or Whitinton; c. 1480 – c. 1553) was an English grammarian. He was a pupil at Magdalen College School, Oxford, where he probably studied under the grammarian John Stanbridge.
In 1513 he was admitted as a BA at Oxford, having studied rhetoric for 14 years, and taught it for 12 years. About 1519 he presented Cardinal Wolsey with a verse and a prose treatise, with a dedication requesting patronage. In the same year he published Libellus epigrammaton, an anthology of poems addressed to Wolsey, Henry VIII, Thomas More, and John Skelton. His Vulgaria, published in 1520, pays compliments to the late king Henry VII, to Thomas Linacre, and to More, who was here first described as "a man for all seasons". Whittington's efforts succeeded by 1523, at the latest, when he enjoyed the favour of Henry VIII.
