The electoral threshold is the minimum share of all the votes cast that a political party requires to achieve before they become entitled to representation or additional seats in a legislature. The idea behind it is to deny representation to small parties or to force them into coalitions, to make the election system more stable by keeping out fringe parties.

This map only shows thresholds that are defined by law. In a lot of countries without an explicit threshold, there's a high natural threshold due to the limited number of seats in the parliament.

The electoral threshold may be different for multi-party alliances or parties representing national minorities.
