The pre-season friendly at London Road comes just a week before both clubs begin their 2012/13 campaigns. Kicking off at 19:45 BST, the match will be shown live on MUTV.
United and Peterborough have family ties of course with Sir Alex Ferguson's son Darren now in his second spell as manager of the Cambridgeshire side.
Darren guided Peterborough into the Championship four months after his return to the club, and kept them in the second tier in 2011/12 with an 18th-place finish. The Posh achieved this with the help of young Reds midfielder Ryan Tunnicliffe, who spent six months on loan at London Road in 2011/12.
August's Friday-night fixture will be the fourth pre-season friendly between the sides in seven years, following warm-up matches in 2005, 2007 and 2008. Ticket details will be announced soon.
