Sir Robert Rich, 2nd Baronet (c. 1648 – 1 October 1699) was an English Whig politician.
His sons were Charles, Robert, Nathaniel, and Cholmondeley, of whom the first two inherited his baronetcy in succession.
Rich was a Whig Member of Parliament for Dunwich and a Lord of the Admiralty during the reign of William III.
He was active in speaking on naval affairs in the House.
On 5 May 1692, he was appointed Vice-Admiral of Suffolk, an office he held until a few days before his death, when he was replaced by his eldest son Charles.
