Every year, millions of Americans prepare for Memorial Day weekend with backyard cookouts, family gatherings, road trips, and seasonal shopping. While many retailers extend their business hours and launch major sales events during the holiday weekend, Costco takes a very different approach. The wholesale giant is known for prioritizing employee time with family during major federal holidays, which means shoppers should expect warehouse closures on Memorial Day 2026 once again.
For loyal Costco members, this annual closure has become part of the company’s culture. Even though many competing stores remain open throughout the holiday weekend, Costco chooses to close all locations nationwide on Memorial Day so employees can spend the day celebrating with loved ones.
That decision may be appreciated by workers, but it also means customers need to plan ahead. Anyone hoping to stock up on grilling essentials, beverages, party supplies, home appliances, or last-minute groceries should make their shopping trips before Monday, May 25, 2026.
This detailed guide covers Costco’s Memorial Day 2026 hours, shopping tips, warehouse schedules, gas station operations, online shopping options, major holiday deals, and the complete list of holidays when Costco stores close every year.
No, Costco will be completely closed on Memorial Day 2026.
All Costco warehouse locations across the United States are expected to shut their doors for the entire day on Monday, May 25, in observance of the federal holiday. This includes warehouse stores, customer service operations inside warehouses, and most supporting services connected to in-person shopping.
Costco has consistently followed this holiday closure policy for years. Unlike some retailers that use holidays as opportunities to attract additional foot traffic and boost revenue, Costco maintains a tradition of giving employees time off during important national celebrations.
Memorial Day honors military personnel who lost their lives while serving in the United States Armed Forces. For many families, the day represents remembrance, appreciation, and quality time together. Costco’s closure policy reflects those values by allowing employees to spend the holiday away from work.
Why Costco Closes on Major Federal Holidays
Costco stands out among major retailers because it closes more frequently during federal holidays than many competitors. While chains such as Walmart, Target, and grocery stores often remain open with adjusted hours, Costco has long maintained a limited holiday schedule.
The company’s approach aligns with its broader reputation for employee-focused policies. Costco is frequently recognized for offering competitive wages, strong benefits, and better working conditions compared to many other retail employers.
Closing stores on Memorial Day serves several purposes:
Supporting Employee Work-Life Balance
Retail workers often miss holidays due to demanding schedules. Costco’s closures allow employees to spend time with family and friends during nationally recognized holidays.
Maintaining Company Tradition
Costco has established a long-standing tradition of closing during select holidays every year. Members have come to expect these closures as part of the company’s operating model.
Encouraging Advance Shopping
Holiday closures also create strong shopping traffic in the days leading up to the event. Members typically stock up in advance on food, drinks, decorations, outdoor products, and seasonal items.
Costco Memorial Day Weekend Hours 2026
Although Costco will close on Memorial Day itself, stores will remain open during the weekend leading up to the holiday.
Customers are encouraged to shop early because warehouses often become significantly busier before major holidays. Parking lots, checkout lines, and gas stations may experience heavy traffic throughout the weekend.

Sunday is the final opportunity for customers to shop in-store before Memorial Day closures begin. Warehouses may experience increased demand for fresh groceries, prepared foods, meat packages, bakery items, and beverages.
Gas stations at Costco locations may also see heavier traffic as travelers prepare for holiday road trips.
Costco Gas Station Hours Before Memorial Day
Costco gas stations often operate with extended hours compared to warehouse stores. However, hours can vary by location.
Many Costco fuel stations are expected to remain open during regular weekend schedules before Memorial Day, though members should confirm exact times through their local warehouse listings.
Because fuel prices at Costco are often lower than nearby competitors, long lines are common during holiday weekends. Filling up earlier in the weekend can help shoppers avoid delays.
