Is Costco Open Today? MLK Day Hours, What’s Different, and How to Confirm Your Local Warehouse

If you’re asking “is Costco open today” on Monday, January 19, 2026, the answer for most shoppers in the U.S. is yes: Costco warehouses are open today because Martin Luther King Jr. Day is not one of Costco’s standard full-closure holidays.

That said, hours can vary by location, and some services inside or adjacent to the warehouse may run on a different schedule than the main store. Here’s what to know before you head out.

Is Costco open today on Martin Luther King Jr. Day?

Yes. Costco is generally open on MLK Day, which is observed on the third Monday in January. Most warehouses operate with regular business hours, and many locations follow a common schedule of 10:00 a.m. to 8:30 p.m. local time on weekdays.

Because Costco runs by warehouse-specific hours, the safest approach is to confirm your exact location’s opening and closing times before driving over, especially if you’re planning to shop early or late.

Why Costco is open today (and the holidays when it’s usually closed)

Costco is known for closing on a short list of major holidays each year. MLK Day typically isn’t on that list, which is why “is Costco open today” is usually a “yes” on this particular Monday.

Costco’s most common full-closure holidays in the U.S. include:

• New Year’s Day

• Easter Sunday

• Memorial Day

• Independence Day (July 4)

• Labor Day

• Thanksgiving Day

• Christmas Day

If today is MLK Day, you’re generally in the clear. If today is one of the dates above, the warehouse is typically closed all day.

Typical Costco hours today: what shoppers should expect

For many U.S. warehouses, a standard weekday schedule looks like this:

• Open: 10:00 a.m.

• Close: 8:30 p.m.

But Costco hours can differ by warehouse and region, and occasional exceptions happen around local events, weather disruptions, or special circumstances. If you’re shopping during peak periods (midday on a holiday), also expect:

• Busier parking lots

• Longer checkout lines

• Faster sell-through on high-demand items (rotisserie chicken, bakery staples, bottled water, popular produce)

Are Costco gas stations, pharmacy, and food court open today?

Even when the main warehouse is open, individual services may keep different hours:

• Gas station: Often open, sometimes with longer hours than the warehouse, but it varies by location.

• Pharmacy: Frequently open on a modified schedule; some locations close earlier than the warehouse.

• Food court: Usually open when the warehouse is open, but it may close a bit earlier than the main doors at certain locations.

• Tire center: Often open, but appointment availability and staffing can be tighter on holidays.

If your main reason for going is gas, prescriptions, or tire service, it’s worth checking that service’s specific hours for your warehouse.

How to confirm “Costco open today” in under a minute

To avoid arriving at a closed door or catching the last 10 minutes before closing, do this quick check:

1. Search your warehouse name or city plus “Costco hours.”

2. Open the official warehouse listing and confirm today’s hours.

3. If you need gas/pharmacy/tire center, check those hours separately.

4. If you’re cutting it close, call the warehouse directly.

Shopping tips for Costco on a holiday Monday

If you’re heading in today, a few small moves can save a lot of time:

For January 19, 2026 (MLK Day), Costco is open today in most places, typically with normal warehouse hours. The only catch is that your local warehouse hours and service hours can vary, so a quick location check before leaving is the best way to make sure your Costco run goes smoothly.
