Eastbourne is a constituency for the House of Commons of the UK Parliament.
It was created as one of nine in Sussex in 1885, since when it has reduced in geographic size reflecting the growth of its main settlement, Eastbourne.
The seat was re-won in 2019 by Caroline Ansell, a Conservative who ousted Liberal Democrat Stephen Lloyd; she earlier did so in 2015.
Since the seat's creation it has been won by candidates from either of these two political parties (and their early forebears, the Liberal Party and the Unionist Party).
The seat has had four by-elections, lastly in 1990.
For 94 years of the 20th Century, the seat was represented by Conservative MPs.
The seat in the 1930s saw three unopposed candidates: in 1932, March 1935 and November 1935.
Eastbourne has been considered relative to others a very marginal seat, as well as a swing seat, since 1997 as its winner's majority has been at most 7.86% of the vote.
A 8.9% majority Tory re-gain took place in 1992 and since 2010 the seat has changed hands (between the two parties mentioned) all four possible times.

Constituency profile
The constituency contains urban and suburban developments, including the whole of the Eastbourne Borough Council administrative area, as well as the village of Willingdon on its outskirts, which forms a small part of the Wealden District Council administrative area.
Eastbourne itself is on the edge of the London Commuter Belt and is a coastal resort town.
The Eastbourne seat has narrowed at every Boundary Commission Periodic Review, as the population of the core town has grown.
Chris Hanretty, the Professor of Politics at Royal Holloway, estimated that Eastbourne voted 57.6% to 42.4% in favour of leaving the European Union during the 2016 referendum.

From safe seat to marginal seat
350px|thumb|Results of all deposit-keeping candidates in their bid be the MP for Eastbourne (UK House of Commons), from and including the 1990 result From 1910 until 1987 the seat returned Conservative Party candidates at every election.
The large rural vote within the seat, until boundary changes in 1983, resulted in strong Conservative support – rural English voters tended to be richer and more right-wing (anti-socialist, pro-Empire before 1960s, pro-Established Church and pro-defence) compared to other voters.
The seat became a marginal, or swing seat, from the 1990 by-election onwards, being closely fought for between the two locally dominant parties.
A Liberal Democrat gained the seat at the 2010 general election, in a vote which saw Eastbourne return the sixth-lowest Labour share of the vote of the 631 candidates who stood at the election, with only 4.8%.
In 2015, the seat was the 9th most marginal of the Conservative Party's 331 seats, by share of the vote.List of Conservative MPs elected in 2015 by % majority  UK Political.info.

Proposal to change constituency name
In 2016 incumbent Ansell made better known via the local press some voters wished the seat's name be changed to add "and Willingdon".
Had this met with enough public support Ansell confirmed she (or anyone else) could apply to the Boundary Commission to request the change.
