(TMZ) - "Real Housewives of Atlanta" star Porsha Williams is a wanted woman ... TMZ reports there's a warrant out for her arrest.

According to TMZ, ATL cops are going after Porsha over a fight she had with Kenya Moore on the set of the show.  Porsha allegedly attacked Kenya, who filed a police report. TMZ reports that the show has the raw footage, and that was enough to charge Porsha with misdemeanor battery -- thus the warrant.

Porsha's lawyer, Joe Habachy, tells TMZ she will surrender Thursday.

TMZ reports that Porsha plans to go after Kenya ... she wants the D.A. to file felony aggravated assault charges against Moore.
