Robert Hay (6 January 1799 – 4 November 1863) was a Scottish traveller, antiquarian, and early Egyptologist.
In 1824 he met Joseph Bonomi in Rome, whom he hired as an artist and who accompanied Hay to Egypt.
They stayed in Egypt from November 1824 until 1828, and 1829 to 1834, recording monuments and inscriptions, and making a large number of architectural plans.
In May 1828 Hay visited Malta, where he married Kalitza Psaraki, the daughter of the chief magistrate of Apodhulo, Crete; Hay had earlier rescued her from the slave market in Alexandria.
After his death in East Lothian, Scotland, in 1863, Hay's collection of Egyptian antiquities was sold to the British Museum, though some objects were purchased by the Boston Museum of Fine Arts in 1872.
