It'll be the 25th year of the awards, which are voted on by the public. ITV says: "A multiple NTA winner himself, David will take centre-stage as host of the UK's leading awards show."
Commenting on his new role, David Walliams says: "I am thrilled to be the new host of the NTAs, and will ensure I will also win them all."
NTA's creator and Executive Producer, Kim Turberville, says: "The National Television Awards are coming soon and we have two more exciting reasons to celebrate in January 2020 - it will be the NTA's 25th anniversary AND our host is the brilliant David Walliams.
"David is a man of so many talents - a comedian, actor, best-selling author, TV judge and charity fundraising hero... and we look forward to him now being the NTA's Celebrator-in-Chief in this very special year."
Voting on the longlist starts later this month.
