Sir Edward Greaves, 1st Baronet (1608 – 11 November 1680), was an English physician.
In the same year he published Morbus epidemicus Anni 1643, or the New Disease with the Signes, Causes, Remedies &c, an account of a mild form of typhus fever, of which there was an epidemic at Oxford that year, especially in the houses where sick and wounded soldiers were quartered.
Of this creation, the first of a physician to that rank, no record exists, but the accurate Le Neve did not doubt the fact, and explained the absence of enrolment.
He delivered the Harveian oration at the College of Physicians 25 July 1661 (London, 1667, 4to), of which the original manuscript is in the British Library (Sloane MS 302).
He became physician in ordinary to Charles II, and owned the lands of St Leonard's Forest in Sussex, including that part which became Leonardslee.
