Our HUGE Adventure, also known as Our Big HUGE Adventure, is a 2005 American interactive animated musical adventure film produced by The Baby Einstein Company and Curious Pictures. It was first released direct-to-video on August 23, 2005. The film was followed by and serves as the pilot of the TV series Little Einsteins.

When it later aired on Playhouse Disney, the movie was split in half as two episodes at the end of Little Einsteins' first season, with many scenes of the original cut being edited out or shortened to fit the show's runtime.

As a requirement for the use of the Einstein name and trademark, the Baby Einstein Company paid royalties to Corbis, which acts on behalf of the estate of physicist Albert Einstein ("Einstein" & "Albert Einstein" being licensed trademarks of The Hebrew University of Jerusalem).

Just like the show that followed, Our Big HUGE Adventure was set to famous classical music pieces and artwork. The movie features Beethoven's Ninth Symphony, and includes artwork such as Wheat Field with Cypresses by Vincent van Gogh, The Great Wave off Kanagawa by Katsushika Hokusai, Woman in the Garden by Claude Monet, and Navajo woven art (the last of which also makes a cameo in the series' intro).
