The news anchor was recently at the centre of speculation that he was considering exiting the NBC morning show once his current contract expires in 2012.
However, during an appearance on Late Night with Jimmy Fallon on Tuesday, he said: "It's not true. I heard the rumour but it's not true. I love my job. I have a long-term contract - I'm not going anywhere."
His comments confirmed Today Show executive producer Jim Bell's recent denial that Lauer will leave the programme.
"When we're talking about something that is almost two years away, it's silly speculation," Bell told The Hollywood Reporter in an interview last week. "I think it's great that the show can generate this much attention and passion out there, but... so much of it has been wrong and misguided."
Lauer appeared on Late Night with Jimmy Fallon dressed in a morning suit in honour of the upcoming royal wedding, which he will cover for NBC.
"I am a method anchor and getting into my role," he joked. "My suit maker at Saville Row has ingeniously crafted a catheter inside my suit. I can't move for seven hours [during the wedding coverage]."
Prince William will marry Kate Middleton at Westminster Abbey on Friday.
