McDonald's Free Cheeseburgers on National Cheeseburger Day

McDonald's is celebrating National Cheeseburger Day by giving away free double cheeseburgers to customers who make a $1 purchase at participating locations.

The promotion takes place on September 18, 2026, and requires orders to be placed through the McDonald's app.

According to a press release, each customer is eligible for one free double cheeseburger per visit, but taxes may still apply and delivery orders are excluded from this offer.
