East Sussex (UK Parliament constituency)

East Sussex (formally the Eastern division of Sussex) was a parliamentary constituency in the county of Sussex, which returned two Members of Parliament to the House of Commons of the Parliament of the United Kingdom, elected by the bloc vote system.

It was created under the Great Reform Act for the 1832 general election, when the existing Sussex constituency was divided into two. It consisted of the rapes of Lewes, Pevensey and Hastings, an area broadly similar to but not identical with the modern county of East Sussex. The "place of election", where nominations were taken and the result declared, was Lewes.

East Sussex was abolished for the 1885 general election, being divided between four new single-member county constituencies, Rye, Eastbourne, East Grinstead and Lewes. (Lewes and Rye also absorbed the voters from the abolished boroughs of the same names.)
