Costco Memorial Day Hours 2026: Is Costco Open Today?

If you’re planning a last-minute warehouse run this holiday weekend, here’s the most important thing you need to know: Costco is closed on Memorial Day 2026. That means no in-store shopping, no gas station, no food court, and no pharmacy on Monday, May 25, 2026. Here’s everything you need to know so you can plan accordingly and still make the most of the long weekend.

Is Costco Open on Memorial Day 2026?

No. Costco warehouses across the United States are completely closed on Memorial Day. This is consistent with the company’s long-standing policy — Memorial Day is one of seven holidays each year when all U.S. warehouse locations shut their doors. According to Costco, stores close on these days so employees can spend time with family and loved ones.

Memorial Day 2026 falls on Monday, May 25, observed annually on the last Monday in May to honor U.S. military personnel who have lost their lives in service to the country.

What Are Costco’s Normal Hours?

To plan your pre- or post-holiday shopping trip, here are Costco’s standard warehouse hours for most U.S. locations:

Hours can vary by location, so it’s always a good idea to check your local warehouse on the Costco store locator before heading out.

Costco Gas Station Hours

Costco gas stations are also closed on Memorial Day, just like the main warehouse. On regular days, gas stations typically open as early as 6:00 AM and close around 9:30 PM on weekdays, with slightly shorter hours on weekends. However, these times vary significantly by location.

Costco Pharmacy Hours

The Costco pharmacy is closed on Memorial Day as well. On normal weekdays, pharmacies operate from 10:00 AM to 7:00 PM, and on Saturdays from 9:00 AM to 6:00 PM. Most Costco pharmacies are closed on Sundays.

When Does Costco Reopen After Memorial Day?

Costco warehouses will reopen on Tuesday, May 26, 2026, during regular business hours. If you missed your chance to shop before the holiday, you’ll be able to head back in bright and early Tuesday morning — Executive Members as early as 9:00 AM, and all other members from 10:00 AM.

Best Time to Shop at Costco This Weekend

Since Costco is closed Monday, your best windows are Saturday, May 23 and Sunday, May 24. These are the final two days before the holiday and are typically very busy, so plan to arrive early. Executive Members can take advantage of early access — starting at 9:00 AM on both days — to beat the crowds.

A few tips for making the most of your pre-holiday trip:

• Go early Saturday morning. It opens at 9:30 AM for regular members and is usually less hectic before 11:00 AM.
• Fill up your gas tank before Monday. The Costco gas station will also be closed on Memorial Day.
• Pick up your prescriptions Friday or Saturday. The pharmacy will be closed for the entire holiday.
• Use Instacart for same-day delivery. Select Costco locations offer same-day grocery delivery through Instacart, which is available even on days when the warehouse is closed.

Costco Memorial Day Sale 2026: Deals Are Still Active

Just because the doors are closed doesn’t mean the savings stop. Costco typically runs a multi-week Memorial Day Sale that extends well before and after the holiday itself. In 2026, the sale is expected to run from approximately May 14 through June 7, featuring some of the best deals of the summer on big-ticket items and everyday essentials.

Highlighted Memorial Day Sale deals currently available include:

• Major appliances — up to $500 off brands like Samsung, LG, and Whirlpool
• Mattresses — significant discounts on popular brands
• Michelin tires — $80 off select sets
• TVs and electronics — smart TV deals under $800

• Freezer pops and summer snacks — great deals for cookouts and gatherings

Costco.com remains fully accessible on Memorial Day, so you can browse and shop online even while the warehouses are closed. Online-only deals are also common during this period, so it’s worth checking the website on the holiday itself.

Stores Open on Memorial Day if You Need an Alternative

If you forgot to grab something before Monday, several major retailers will be open on Memorial Day 2026 with varying hours:

• Walmart — Open regular hours, typically 6:00 AM to 11:00 PM
• Target — Open, though some locations may have reduced hours
• Sam’s Club — Expected to be open with holiday hours
• Trader Joe’s — Open at most locations
• Home Depot — Open during normal business hours
