Robert Abraham (1773–1850) was an English building surveyor and later architect in London. He was the son of a builder and was educated as a surveyor as a pupil of James Bowen. He turned to architecture after 1818, and was chiefly employed by the leading Roman Catholic families in England, including the Duke of Norfolk and the Earl of Shrewsbury. Among Abraham's students was the architect James Lockyer who went on to form his own successful London practice.
