All 50 states have state constitutions, and all of these constitutions allow for amendment.

• Read more about amending state constitutions here.

State amendments are not tracked well in most states. Constitutions are typically published online, with varying sources, formats and functionality; constitutional amendments, however, are not often clearly tracked. Below are some currently available resources for amendments in each state.

NOTE: Ballotpedia may also list some amendments. Some state legislatures offer databases of legislation that can be searched for constitutional amendments.
