The Netherlands international has been signed up by the broadcasters after helping the Red Devils clinch the title with a hat-trick against Aston Villa on Monday.
It was confirmed today that Van Persie will join Tottenham Hotspur star Gareth Bale in the advertising campaigns for their coverage, which includes 38 live Premier League games a season for three years.
"I am thrilled to be joining BT Sport as one of the faces of their advertising," said Van Persie. "It has been great fun filming the adverts and shooting the posters and I know fans will be seeing some amazing footage and pictures when the adverts start to appear."
Head of BT Sport Simon Green added: "I am absolutely delighted that we have signed a star of Robin's calibre to be in our advertising. There are few current players that have had such an incredible run of form in the Premier League over the last couple of seasons.
"For BT Sport, Robin is one of the players that embody the dynamism and skill that we are going to be showcasing with our live coverage, so we could not have signed a more powerful figure."
