The Holland midfielder has been linked with a summer move away after a diffcult past season.
However, the appointment of new coach Hansi Flick has offered De Jong a fresh spring in his step.
He explained to Mundo Deportivo: "Staying at Barca? Yes, I’m very happy in Barcelona with my family, for sure. Hansi Flick wants me to be key? I talked to him, it was good.
"After the European Championship we will see how he is doing."
Barca president Joan Laporta also said: "The last thing he would want would be to leave Barcelona," the 61-year-old confirmed. "He has told me more than once, that he is delighted here.
"We have margin. We are delighted with him. I'm not worried about anyone and if someone wants to leave, we can't go against a player's will. But I think everyone wants to stay and we want everyone we have to stay. We don't want any of them to leave, because no team in history has been a flash in the pan."
