Dan Green (born February 7, 1975; San Rafael, California, United States) is an American voice artist. He works for 4 Kids Entertainment, a company known to disappoint fans of anime.

He is the current English voice of Knuckles the Echidna, from the Sonic The Hedgehog video games series. He also did the voice of Knuckles in the anime Sonic X.

Dan's most famous role is that of Yugi Mutou from Yu-Gi-Oh!.

Most fans give Dan respect, because he has done many great roles, but they don't think Knuckles is one of them. This is because he uses the wrong character, as he sounds too close to Yugi Mutou.

In Sonic The Hedgehog (2006), Dan is credited as Jay Snyder. This also caused some confusing with the media, as it was rumored Knuckles is voiced by someone else in this game only.
