McDonald’s Shamrock Shake usually leaves menus shortly after St. Patrick’s Day, so for 2026 you should expect it to be gone sometime in late March, depending on your local restaurant’s supply.

Quick Scoop

  • The Shamrock Shake returns to U.S. McDonald’s locations on February 17, 2026.
  • It’s a limited-time item with no fixed nationwide end date announced.
  • Official info says it’s guaranteed to be around through St. Patrick’s Day (March 17) and then “while supplies last.”
  • In practice, many stores stop offering it in the last part of March once ingredients run out.

So if you’re wondering “when does the Shamrock Shake leave?” in 2026, plan to grab one before or around March 17, and don’t be surprised if your local spot stops serving it at any point in the weeks after, once their stock is gone.
