Cumulative voting (also accumulation voting or weighted voting) is a multiple-winner voting system intended to promote proportional representation while also being simple to understand.

A cumulative voting election elects the top vote-getters, just as with a simple plurality election. However, voters are allowed to concentrate their full share of votes on fewer candidates than seats -- unlike bloc voting, where a voter can only award one vote per candidate, up to the number of candidates as seats. With cumulative voting, voters are permitted to not split their votes and instead concentrate them on a single candidate at full value.
