List of Wyoming ballot measures

The U.S. state of Wyoming has had a system of direct voting since 1968, when voters adopted a constitutional amendment allowing measures to be placed on the ballot. Only years when ballot measures were on the general election ballot are listed.

Background
Wyoming's ballot measure procedure has been described by the Initiative & Referendum Institute as "one of the most onerous" in the nation. In order to place a citizen-initiated initiative on the ballot, measure sponsors must gather signatures equal to 15% of ballots cast in the previous election, along with at least 15% of voters in two-thirds of Wyoming counties. These requirements, coupled with the legislature's ability to remove ballot measures if they adopt a substantially similar law, make placing measures on the ballot exceptionally difficult. As a result, most measures voted on in the general election are placed on the ballot by the legislature, not the voters.

There are three types of ballot measures in Wyoming:


 * Initiated state statues are measures that would create new state law. They are sponsored by voters and placed on the ballot after meeting signature requirements.
 * Legislatively-referred constitutional amendments are changes to the Wyoming Constitution and are automatically placed on the ballot after approval by the legislature.
 * Veto referenda are measures to repeal state law. They are sponsored by voters and placed on the ballot after meeting signature requirements.
