The title Earl of Bridgewater has been created twice in the Peerage of England. It was first created in 1486 for Henry Daubney, 9th Baron Daubney . That creation became extinct in 1548. It was then created in 1617 for John Egerton, 1st Viscount Brackley . The fourth earl was created Duke of Bridgewater in 1720 with the subsidiary title Marquess of Brackley. These creations became extinct in 1803. The earldom became extinct in 1829.

A scoundrel claiming to be the long-lost but rightful Duke of Bridgewater appears in the 1885 novel The Adventures of Huckleberry Finn by Mark Twain, which is set before the American Civil War.

The original spelling is likely to have been Bridgwater, meaning the burg of Water, and the same as Bridgwater in Somerset (see archive reference 2/79).
