County introduction

The Lake County Clerk’s official election resources provide county voting information.

Upcoming elections

Illinois schedules the Consolidated Election for April 6, 2027. The February 23, 2027 Consolidated Primary applies where a primary is required. Confirm the applicable election with the Lake County Clerk.

November 3, 2026 has passed. Contact the appropriate election authority for the next applicable election, official notices and deadlines. A future county election date was not confirmed in this bounded refresh. Historical reference for the completed November 2026 election: The county’s official page identifies the November 3, 2026 General Election. It provides candidate and referendum resource links; this guide does not certify the underlying lists or individual applicability.

Register to vote

Illinois offers online, mail and in-person registration. For in-person registration, provide two identification documents, ordinarily including one showing your current residence address. Applicants experiencing homelessness may use evidence of their stated mailing address to satisfy the address-document requirement. The two-document requirement still applies. Ask the County Clerk about acceptable documents.

For April 6, regular registration at the election office or through a deputy registrar closes March 9. Online registration closes March 21. Grace period registration and voting runs March 10 through April 6 at designated locations. For an applicable February 23 primary, those dates are January 26, February 7 and January 27 through February 23, respectively. Confirm the deadline for your registration route and the grace period site with the County Clerk.

Find your polling place or voting location

Use the official early-voting and election resources for locations. Confirm site-specific hours before traveling.
