Is Costco Open on Memorial Day?
No. Costco will be closed on Memorial Day this year, just like every other year.
The retailer lists Memorial Day among the seven holidays when all U.S. warehouse locations close for the day. Costco says stores will close so employees can spend time with family and loved ones.
Memorial Day is one of the company's regular annual holiday closures, alongside holidays like Thanksgiving, Christmas Day and Independence Day. According to Costco's holiday schedule, all U.S. warehouse locations will be closed on Monday, May 25, 2026.
That means shoppers hoping to grab last-minute barbecue essentials, desserts, drinks, or party supplies will want to make their Costco run before Memorial Day arrives.
