The shock jock - who joined Sharon Osbourne and Howie Mandel on the panel last season - had previously admitted that he didn't know whether he would be back.
However, NBC's president of alternative and late night programming Paul Telegdy confirmed today that Stern will return to the show.
"Howard Stern's towering presence and opinions on last season's show as a new judge made a dramatic impact and added a sharper edge to the fascinating developments on stage," he said.
"We know that Howard believes in America's Got Talent - which remains America's top-rated summer series - and that dedication comes across in a genuine way to our viewers who share his passion about our amazing talent competition."
Meanwhile, Stern said on his Sirius XM radio show that he is "very, very excited" about returning to the competition, E! Online reports.
Osbourne is not expected to return to America's Got Talent this season after she announced that she was leaving in protest at NBC, whom she alleges fired her son Jack Osbourne after discovering that he had been diagnosed with MS.
Stern has previously said that he would love Osbourne to change her mind and come back to the show.
