Mickey Mouse Mixed-Up Adventures is an American animated children's television series that was broadcast on Disney Junior. Produced by Disney Television Animation, the series is the successor to Mickey Mouse Clubhouse. Originally airing as Mickey and the Roadster Racers for its first two seasons, it debuted on its first two episodes consecutively on January 15, 2017.

The series was renewed for a second season on March 15, 2017 which premiered on April 13, 2018. The show’s third season was renewed one year later, which led to the series being renamed to Mickey Mouse Mixed-Up Adventures. The first episode under the new title was originally broadcast on October 14, 2019.

This was Russi Taylor's final television series role before her death on July 26, 2019. It is also the only series produced since 1985 not to feature Tony Anselmo as Donald Duck due to him being too busy providing the voice for the character in other Disney projects, including DuckTales and Kingdom Hearts III; Daniel Ross voices the role of Donald in this series.

The show was followed by a new series, Mickey Mouse Funhouse, which debuted on August 20, 2021. In 2021, two spin-off holiday specials were released: a Halloween special, Mickey's Tale of Two Witches, on October 7, 2021, in addition to a Christmas special, Mickey and Minnie Wish Upon a Christmas, on December 2, 2021.
