Griffin began the 2014 season as Washington's starting quarterback before dislocating his ankle in Week 2 and missing six games. He took his job back upon returning before temporarily losing it down the stretch.
"We'll go into the season with Robert as our No. 1 guy," said Gruden.
Quarterbacks Kirk Cousins and Colt McCoy both saw playing time last season when Griffin was sidelined. Cousins went 1-4 in his five starts before being benched in favor of McCoy, and did not see the field again in 2014. In December, Cousins said that he will request a trade if he's not named the starter next season.
Griffin was benched in favor of McCoy in Week 12, but McCoy injured his neck in Washington's Week 14 shutout loss to the St. Louis Rams and was placed on injured reserve. The 28-year-old is set to become a free agent in March.
Griffin finished the 2014 season with 1,694 yards, four touchdowns and six interceptions.
