The McDonald’s Grinch Meal in 2025 does not have one single, universally fixed end date, but the best guidance is that it runs from December 2, 2025, through Christmas Day, December 25, 2025, at participating U.S. locations, and only while supplies last. Some coverage also notes there is “no official end date,” emphasizing that it is a limited‑time promotion that can sell out earlier depending on demand and inventory.

Official timing

  • Multiple news outlets report that the Grinch Meal launches on Tuesday, December 2, 2025, at participating McDonald’s restaurants in the U.S.
  • At least one detailed write‑up citing McDonald’s social channels says it is available “until Christmas Day, December 25, 2025,” with the usual caveat of “while supplies last” and “participating locations only.”

“Limited time” and sell‑outs

  • Some reporting and reviews stress that McDonald’s did not lock in a hard published end date beyond describing it as a limited‑time holiday offer, meaning stores can run out of promo items or stop advertising it earlier.
  • Coverage of early sales indicates the Grinch Meal has been very popular and “won’t last long,” with marketing leaders warning that supplies may dwindle quickly and advising customers to get it sooner rather than later.

Practical takeaway

  • If you want the 2025 Grinch Meal, plan on it being available from Dec 2 through around Christmas Day at U.S. McDonald’s, but do not assume every store will have it right up to December 25.
  • The safest move is to check your local McDonald’s app or restaurant early in December, because locations can sell out of socks and other promo components before the official window ends.
