The secret ballot, also known as the Australian ballot,^[1] is a voting method in which a voter's identity in an election or a referendum is anonymous. This forestalls attempts to influence the voter by intimidation, blackmailing, and potential vote buying. This system is one means of achieving the goal of political privacy.

Secret ballots are used in conjunction with various voting systems. The most basic form of a secret ballot utilizes paper ballots upon which each voter marks their choices. Without revealing the votes, the voter folds the ballot paper in half and places it in a sealed box. This box is later emptied for counting. An aspect of secret voting is the provision of a voting booth to enable the voter to write on the ballot paper without others being able to see what is being written. Today, printed ballot papers are usually provided, with the names of the candidates or questions and respective check boxes. Provisions are made at the polling place for the voters to record their preferences in secret, and the ballots are designed to eliminate bias and prevent anyone from linking voters to the ballot.

A privacy problem arises with moves to improve the efficiency of voting by the introduction of postal voting and remote electronic voting. Some countries permit proxy voting, but some argue this is inconsistent with voting privacy. The popularity of the ballot selfie has challenged the secrecy of in-person voting.

In systems of direct democracy, such as the Swiss Landsgemeinde, voting is typically conducted publicly to ensure all citizens can observe the outcome.
