The '''Single Transferable Vote''', or '''STV''', is a [[preferential voting|preferential]] [[voting system]] designed to minimise wasted votes in multi-candidate elections while ensuring that votes are explicitly for candidates rather than party lists. |

When promoted as a [[proportional representation]] method in multi-party multi-seat elections, it is generally known as '''Proportional Representation through the Single Transferable Vote''' or '''PR-STV'''. When a similar method is applied to single-seat elections it is sometimes called ''[[instant-runoff voting]]'' or the ''alternative vote'', and has different proportionality implications for a similar ballot. |
