Robert of Orford (), also called Robert of Oxford, Robert of Colletorto or Robert of Torto Collo, was an English Dominican master of theology at the University of Oxford and an early defender of Thomas Aquinas.
Robert studied at either Oxford or Cambridge, and is said to have been a bachelor of divinity. He may have afterwards gone to the University of Paris before returning to Oxford, but this conjectural. The date at which he became a master is unknown. He was the in a disputation with a certain Richard Clive (known from a Cambridge manuscript) and another with Alan of Wakerfield, the Franciscan master of theology at Oxford, around 1285. He preached a sermon at Oxford on 22 February 1293.
Robert's name is incorrectly given as William in one manuscript. Leandro Alberti placed his activity as early 1242, but all other evidence puts it much later.

There is general consensus that Robert's surviving writings seem to have been written in a hurry, resulting at times in superficiality.
The and are listed under Robert of Orford's name in the 14th-century Stams Catalogue of Dominican authors. The 16th-century bibliographer John Pits records that he also wrote against James of Viterbo. The treatise , formerly attributed to Aquinas, may be by Robert.
