Roethlisberger's future had been the subject of speculation after the 35-year-old hinted he could retire following the Steelers defeat to New England in the AFC Championship game.
However the two-time Super Bowl winner confirmed on Twitter that he is set to return next year.
"Informed the team I am looking forward to my 14th season. Steeler Nation will get my absolute best! -- Ben," Roethlisberger tweeted.
In January, Roethlisberger, who has been dogged by injuries in recent seasons, said he would take time to discuss his future with his family.
"To consider health, and family and things like that and just kind of take some time away to evaluate next season, if there's going to be a next season," he said.
Roethlisberger threw for 3,819 yards and 29 touchdowns in 14 games in 2016.
He underwent surgery to repair a torn meniscus in October, and in 2015 missed four weeks of the season with a badly sprained knee. He also suffered a concussion in 2015 but did not miss any games as a result.
The quarterback is the Steelers' all-time leader in passing yards and touchdowns with 46,814 and 301 respectively, amassed over 13 seasons in Pittsburgh.
