A winner-take-all electoral system is one where a voting bloc can win all seats in a legislature or electoral district, denying representation to any political minorities. Such systems are used in many major democracies. Such systems are sometimes called "majoritarian representation", though this term is a misnomer, as most such systems do not always elect majority preferred candidates and do not always produce winners who received majority of votes cast in the district, and they allow parties to take a majority of seats in the chamber with just a minority of the vote.

Any election with only a single seat is a winner-take-all system (as it is impossible for the winner to take less than one seat). As a result, legislatures elected by single-member districts are often described as using "winner-take-all". However, winner-take-all systems do not necessarily mean the majority of voters are represented properly. A minority of voters across the country may take all the seats; a minority of votes cast in a district may elect all the winners in a district. Conversely, a party with just a sliver of votes in a country-wide sense may have local dominance and take a seat in a particular constituency.
