- The Oregon Constitution can be amended in three ways:

- Initiated constitutional amendment: Citizens can initiate constitutional amendments in Oregon.
- Convention-referred constitutional amendment: A state constitutional convention can vote to refer constitutional changes to the ballot.
- Constitutional revision questions: The state Legislature can propose a revision of part or all of the constitution by a 66.67% supermajority vote of the state legislature and a simple majority vote of the electorate on the revision question.
- The amendment becomes part of the constitution if a majority of those voting on the measure vote for it.
