You can stream the movie Elf in the U.S. on Max (formerly HBO Max) and via Hulu if you add the Max/HBO add‑on, and you can also rent or buy it digitally on most major storefronts like Amazon, Apple TV, Google Play, YouTube, and Vudu. Availability can change each holiday season, so it is always a good idea to check your preferred streaming app directly by searching for “Elf (2003)” just before you watch.
