Goals from Elliot Lee, Paul Mullin (2), an own goal by Ryan Innis, Ryan Barnett, and Jack Marriott sealed the win.

The defeat left Forest Green on the brink of relegation.

Phil Parkinson's team's promotion is their second in a row, following their National League title win last season.

Fans rushed onto the pitch to celebrate after the final whistle.

Wrexham, which is owned by Hollywood stars Ryan Reynolds and Rob McElhenney, will return to English football's third tier for the first time since 2004.

Wrexham, with five wins in their last eight games, were in control of their own promotion destiny in League Two.

After securing a play-off spot with a 4-1 win over Crawley Town, they needed just five more points from their final three games to ensure automatic promotion.

To achieve this, they had to win against Forest Green and hope for dropped points from rivals MK Dons and Barrow.

Forest Green, on the other hand, were struggling at the bottom of the table, having lost four of their last five games.

Wrexham started strongly against the home team but had only a few chances to show for their dominance in the opening quarter of an hour.

The home team then scored the first goal after a corner kick was not cleared, allowing Lee to poke in the ball from close range.

Wrexham's top scorer, Mullin, had a shot blocked but later scored the second goal from a distance.
