Costco will be closed on May 26 due to the Memorial Day holiday. It will reopen the next day on Tuesday, May 27. So if you need to buy those hot dogs, burger buns, paper plates and corn-on-the-cob for your barbecue, either plan to shop at Costco before May 26 or plan to shop at an alternative store.

Costco is following the tradition of closing all stores for major holidays, and the same will be true this month.

Costco will close all stores on Memorial Day 2025, continuing its tradition of honoring major US holidays. While the retailer steps back for a day, analysts say it is poised to thrive under Trump-era tariffs.
