Latics will host Australian side Melbourne Heart in a pre-season friendly set to take place on Saturday, July 19.
Heart, who play their football in the Hyundai A-League, will travel to Boundary Park as part of their pre-season tour.
Damien Duff is expected to sign for the Australian side this summer, whilst former Liverpool and Leeds midfielder Harry Kewell ended his playing career with Heart last season.
This game will give manager Lee Johnson a chance to assess his squad ahead of the 2014/15 campaign.
Kick off for the game is 3pm.
