Party-list proportional representation systems are a family of voting systems emphasizing proportional representation (PR) in elections returning multiple candidates (e.g. elections to parliament). They can also be used as part of mixed additional member systems.

In these systems, parties make lists of candidates to be elected, and seats get allocated to each party in proportion to the number of votes the party receives. Voters may vote directly for the party, as in Israel, for candidates and that vote will pool to the party, as in Turkey and Finland, or for a list of candidates, as in Hong Kong.

The order in which a party's list candidates get elected may be pre-determined by some method internal to the party or the candidates (a closed list system) or it may be determined by the voters at large (an open list system).

List proportional representation may also be combined in various hybrids, e.g. using the additional member system.
