Katt Williams -- I'm UNRETIRED!!!

Just like Michael Jordan, Jay-Z, Evander Holyfield and Brett Favre ... comedian Katt Williams is officially UNRETIRING ... just four days after retiring.

Earlier this week, a very emotional Katt announced his retirement on a street corner in Seattle ... insisting that he was, "kinda done."

But now, Katt's management team says he's undone ... telling us, "Katt is definitely NOT retiring. He will be moving forward with the tour ... Friday is Texas, Saturday New Orleans, and on to Alabama."

Management adds, "The reason why he made remarks was due to him feeling totally disrespected by all the things that happen to him in the city of Seattle. He had a moment where he felt very unappreciated. He now just wants to move forward from those unfortunate events and give his fans outstanding shows from this point forward."

Katt has also not retired from dealing with court ... TMZ has learned Williams was just charged with 2 counts of 4th degree misdemeanor assault in Seattle stemming from a bar fight this past weekend.

As we reported, Katt was arrested Sunday after allegedly threatening the bar manager with a pool cue and refusing to leave the establishment ... then later throwing a cigarette at a woman's eye.

Police claim Katt also threw a rock at the woman's car as she left.
