Illinois Deer Season 2026-27: Archery & Gun Dates

Q: When does deer season open in Illinois in 2026-27?

It depends which season you mean, which is why this page splits them. Deer Archery: October 1, 2026 to January 17, 2027. Firearm Deer Season: November 20, 2026 to December 6, 2026. Illinois Department of Natural Resources publishes both, and the full zone tables on this page were read from its own page on September 2, 2026.

Q: When is firearm deer season season in Illinois?

November 20, 2026 to December 6, 2026. Illinois Department of Natural Resources calls it the Firearm Deer Season season; the exact wording matters because states name the same thing differently, and this page keeps the agency's own name for it.

Q: Does Illinois have a separate muzzleloader or youth deer season?

Muzzleloader-Only Deer Season: December 11, 2026 to December 13, 2026. Youth Firearm Deer Season: October 10, 2026 to October 12, 2026. Both were read from the same agency source as the archery and firearms windows.

Q: Which deer zone am I in, in Illinois?

Illinois sets different dates by zone, and the boundaries are the agency's own, drawn along highways, rivers and county fragments, and they can differ between weapon seasons inside the same state. Your zone is determined from the agency's own map: Illinois Department of Natural Resources publishes the official zone map and boundary descriptions, linked from this page.

Q: Where are the bag limits, antler restrictions and license rules for Illinois?

At Illinois Department of Natural Resources, whose regulations page is linked on this page. Those rules are legally binding, change annually and vary by zone and by land ownership. This page carries the season windows themselves, with source and read date attached.

Q: Can these Illinois deer dates change?

Yes. Agencies amend proclamations, add or drop zones, and occasionally correct their own published tables mid season. This page covers the 2026-27 season year with data as of September 2, 2026, says so in the copy, and links the exact Illinois Department of Natural Resources page it read on September 2, 2026. Treat the agency page as the final word on the morning you hunt.

Other Illinois deer seasons the agency names

Beyond the four main windows, Illinois Department of Natural Resources dates one further season for deer. They are reproduced here under the agency’s own names, because a hunter reading a calendar needs to know which window a tag actually covers.

Zones

Illinois deer zones

Illinois does not have a deer season. It has 2 of them, and the boundaries between them were drawn by Illinois Department of Natural Resources along highways, rivers and county fragments rather than anything you can see from a stand. In several states those boundaries are not even the same from one weapon season to the next.

This page publishes the agency’s zone names and links the agency’s own zone map, which is where a hunter’s zone is determined. A wrong zone answer is a wrong season date.
