Join the Party!

Thank you for considering joining the Green-Rainbow Party. Below you'll find the two ways you can join today.


If you are at least 18 years old and are a citizen of Massachusetts, the easiest way to join the party is by registering to vote Green-Rainbow.

Please download the registration form, which can be used either by new voters or by existing voters wishing to join us. It can be mailed to the Elections Division in Boston (the form is pre-addressed), or it can be brought to your local elections office (usually at Town or City Hall). There are additional special instructions provided for Massachusetts voters.


If you are not registered to vote in Massachusetts, or if you are registered “Unenrolled,” you may secure membership in the party through annual dues by following the instruction on the dues membership form.

Please contact our Membership Director if you have any questions about joining the Green-Rainbow Party.
