Winter X Games XX (re-titled Winter X Games Aspen '16; styled as Winter X Games Twenty in the official logo) were held from January 28 to January 31, 2016, in Aspen, Colorado.

They were the 15th consecutive Winter X Games held in Aspen.

Note: The competition was limited to 1st run scores due to halfpipe conditions becoming unsatisfactory because of inclement weather.

Joe Parsons won the gold medal by doing an amazing trick that he landed sitting with his back towards the handle bars.
