Saturday Night Takeaway has been shortlisted for Best Entertainment Programme at the awards ceremony, which will take place later this year.
The nod comes just days after Dec hosted the ITV without Ant, who stepped down from all TV commitments following his drink-drive charge last month.
The series will go up against Britain’s Got Talent, which is also hosted by the Geordie duo.
Michael McIntyre’s Big Show and The Voice UK also received a nomination in the entertainment category.
Dec is set to present Saturday Night Takeaway alone once more for the series finale in Florida this weekend.
It comes after it was reported that Dec will host Britain’t Got Talent alone.
A TV insider commented: “After last weekend the feeling is very much that Dec should take on BGT alone too – he did a brilliant job.
“The bosses at ITV loved him and want him back on screens as soon as possible, and Simon Cowell totally agrees that he’s the best man for the job rather than bringing in a new face.”
The source added to The Sun: “It was obviously strange for viewers seeing him alone at first, but he took everything in his stride like a pro.
“That’s not to say people didn’t miss Ant, but the overwhelming response was that Dec was fantastic solo too.
“It also solves the major headache over continuity issues because so much of the series is already in the bag after the auditions finished.”
Following the nominations, bookmakers Ladbrokes believe the duo are odds-on for a BAFTA win.
Alex Apati said: “It’s been a tough year for TV’s favourite duo but the odds suggest nothing will stop them from claiming yet another BAFTA.”
Meanwhile, the BAFTA TV nominations also saw The Crown receive three nods.
Actress Claire Foy, who took on the role of Queen Elizabeth, was nominated in the Leading Actress category, while Vanessa Kirby who starred as Princess Margaret received a nod in the Supporting Actress category.
The show has also been nominated for best Drama Series.
BBC series Line of Duty also received three nominations for Drama Series, Leading Actress and Supporting Actor.
Following the nominations, BAFTA chair Jane Lush said she believed the British TV industry is in “pretty good health”.
When asked if the TV awards would follow the lead of the film awards, which saw stars wear black on the red carpet in support of the Time’s Up movement, Jane commented: “I don’t know yet.
“Nobody was forced to wear black at the film awards but we were all delighted to stand up and be associated with the Time’s Up movement.
“The problems that the film industry had to face are universal.
“They’re not just in the creative industries. It’s something that BAFTA takes very seriously. Everybody should be able to go to work feeling comfortable.
