At the WrestleMania 33 pay-per-view on April 2, 2017, Hardy made his surprise return to WWE, along with his brother Matt Hardy, being added as last-minute participants in the ladder match for the Raw Tag Team Championship, defeating Luke Gallows and Karl Anderson, Cesaro and Sheamus, and Enzo Amore and Big Cass to win the Raw Tag Team Championship.
Also, it was their first win as a team at WrestleMania, as well as Hardy's first victory at WrestleMania.
The next night on Raw, The Hardy Boyz successfully defended the title against Luke Gallows and Karl Anderson.
At Payback, The Hardy Boyz retained their championships against Cesaro and Sheamus, who attacked them after the match.
The next night on Raw, Cesaro and Sheamus explained their actions, claiming the fans were more supportive of 'novelty acts' from the past like The Hardy Boyz, who they feel did not deserve to be in the match at WrestleMania 33.
Subsequently, at Extreme Rules, The Hardy Boyz lost the titles against Cesaro and Sheamus in a steel cage match, and failed to regain it back the following month at the Great Balls of Fire event.

On the August 28 episode of Raw, Hardy won a battle royal by last eliminating Jason Jordan to become the number one contender for the Intercontinental Championship, but was unsuccessful in his challenge the following week.
In September, Hardy suffered a shoulder injury and it was reported that the injury would sideline him for four to six months.
On January 22, 2018, Hardy made a special appearance on the 25th-anniversary episode of Raw in a poker segment also involving The APA, Ted DiBiase, and many other wrestlers.
On the March 19 episode of Raw, Hardy also made a cameo appearance in a segment, calling "The Ultimate Deletion" between Matt Hardy and Bray Wyatt, allowing his brother Matt to pick up the victory.
