Season 6 of Arthur premiered in the United States on September 24, 2001 on PBS.
Starting with this season, the color palettes for the characters were given brighter touches and better colors.
This was the first season in which Arthur had a new voice actor, Justin Bradley. Mark Rendall, the voice actor for Arthur in seasons 7 and 8, later redubbed the voice of Arthur in this season after Bradley's was unfavorable.
Among other firsts in this season, the following are introduced:

- This season is the first and only one to feature Justin Bradley as the voice of Arthur, taking over from Michael Yarmush whose voice matured in 2000 (season 5) and the first season where Samuel Holden voices Timmy Tibble instead of Ricky Mabe.
- When Mark Rendall took over voicing Arthur in the following season, he re-dubbed Bradley's dialogue for syndication, though it is retained in international airings and home releases.
- Some episodes are broadcast with DVS narration on PBS (where available) and the Justin Bradley version is still in tact on the secondary audio track.
- This season is the second and last one to feature Steven Crowder as The Brain.
- This season is also the last one to feature Oliver Grainger as D.W. and Jonathan Koensgen as Tommy Tibble.
- This season's end credits originally used a remixed end theme music, containing the original theme song mixed with Francine's "You Can Fly If You Try" soul music as well as D.W. chanting "Yeah, Mama!". It was replaced during U.S. second run syndication in the mid-2010s.
