Is Costco Open on Labor Day 2026?

Why I looked this up

I wanted to know whether a Costco trip would be possible on Labor Day, so I checked Costco’s own holiday policy rather than relying on search trends or recycled store-hours lists.

The short answer

No. Costco’s official holiday-closures page says its U.S. warehouses are closed on Labor Day.

For 2026, the U.S. Office of Personnel Management’s federal holiday schedule lists Labor Day as Monday, September 7, 2026. That means Costco’s U.S. warehouses are closed that day.

My quick decision checklist

Question	What I found
Is Labor Day on September 7 in 2026?	Yes. OPM lists Monday, September 7, 2026.
Is the main Costco warehouse open?	No. Costco lists Labor Day among the holidays when its U.S. warehouses are closed.
Where should I check location-specific details?	Costco’s warehouse locator says to select a local warehouse to see its hours and upcoming holiday closures.

My practical conclusion is straightforward: I would not plan an in-warehouse Costco shopping trip for Labor Day. I would move it to another day and check the selected warehouse page before leaving.

What I looked into further

I also wondered whether the word “warehouse” should automatically be read as a universal schedule for every Costco-associated service. Costco’s holiday policy specifically states that U.S. warehouses are closed, while its locator provides location-level hours and service information.

Because those statements have different scopes, I would not assume that every separately listed service follows one nationwide schedule. For a gas station, pharmacy, tire center, or other department, the careful approach is to open Costco’s warehouse locator, search by city, state, or ZIP code, and review the selected location’s posted details.

The main answer, however, does not require guesswork: Costco’s U.S. warehouses are closed on Labor Day 2026.
