Adventures of Sonic the Hedgehog (promotionally titled Sega's Adventures of Sonic the Hedgehog) is an American animated series that was first broadcast in September 1993. It follows the escapades of the video game character Sonic the Hedgehog, and his sidekick Tails, as they attempt to stop the evil Doctor Robotnik and his array of robots from taking over the planet Mobius.

Another series featuring Sonic, simply titled Sonic the Hedgehog, was aired concurrently. Unlike the other series, Adventures had a light-hearted tone and quirky storylines that portrayed Sonic as being skilled and clever, whereas Robotnik and his robot allies Scratch and Grounder were clumsy.

Adventures of Sonic the Hedgehog was created by DIC Entertainment and Sega Corporation, which produced a total of 66 episodes for its first season, and was syndicated by Bohbot Communications, now BKN International (in the original run, every episode began and ended with the "Bohbot Entertainment Presents" logo). Another cartoon series based on Sonic, simply titled Sonic the Hedgehog, was produced and launched on ABC's Saturday morning line-up. Animator Pierre De Celles said in an interview that neither he nor the rest of the staff working on Adventures of Sonic the Hedgehog knew about or competed with the other series, which he describes as "serious and heavy"; he also described the staff as too busy to pay attention to the other series. In addition to the original 65 episodes, DiC also produced an additional episode that originally aired in winter 1996, "Sonic Christmas Blast", which included aspects of the other Sonic the Hedgehog cartoon such as the city of Robotropolis, SWATbots, and a non-speaking cameo by Princess Sally Acorn. The good thing about Adventures of Sonic the Hedgehog was its comedy.

The one huge flaw AoStH had was its animation. The animation seemed to lack effort at times, and seemed very rushed. Considering this is an early 90's animation, it's really outdated for its time. Dic's budget was pretty low on AoStH, but nicer animation would've been, well, nicer.

Overall, though, if you can just deal with the rushed art, AoStH is a fun series to watch. With a great cast of characters, immense humor, and surprisingly original episodes at times.

Animator Pierre De Celles described the show as "fun and humorous". Episodes of the show normally revolved around Sonic and Tails foiling Robotnik's latest villainous scheme to dominate the zany, colorful world of Planet Mobius. At the end of each episode, Dr. Robotnik's plan would ultimately fail due to Sonic's efforts and his own incompetence.
