Chicago, Illinois voters must meet state and local residency and eligibility rules before registering to vote. This guide explains who may register, how residency is established for local elections, common registration deadlines, and where to file official forms. It draws on official election authorities for Illinois, Cook County, and the City of Chicago so you can complete registration, verify your precinct, and plan for upcoming elections with confidence.

Confirm your registration address with an official election office before the deadline.
