The former Toon midfielder was handed a 12-game suspension following his red card and subsequent violent reaction in the club's 3-2 defeat to Manchester City on the final day of the Premier League season.
As his QPR team-mates continue their pre-season preparations, Barton will work on his fitness with the Lancashire club, who won the Blue Square Premier last season.
Joey Barton (on Twitter): "Looking forward to training with Fleetwood Town for the week. Will get a much needed sweat on...
"Still have 3 years left at QPR. Exciting times for the club, which I intended to be a part of. Need to get some fitness in the meantime...
"Fleetwood are a young club going places. 5 promotions already in the last few years. If I help some of their young players, great.
"Training with them will certainly help me with my short term fitness and my plan on being as fit as possible during my 12-game ban."
