The film by Antidote shows holidaymakers holding their right arm across their chest singing about the features of the site, and its value for money.
At the end the viewer finds out that the people are proud citizens of The Travel Republic and they are singing about all the great things the land has to offer.
The ad was created by Meigan Brown and Tobias Owen. It was directed by Oscar Cariss through Annex, with media planning and buying handled by Arena.
The spot will air on 18 January, and the campaign will run across radio, digital and social media.
Caroline Pay, the head of brand marketing at Travel Republic, said: "We’re always championing for better holidays to ensure our customers get the holiday they really want.
"By portraying The Travel Republic as the land of holidays, and creating a national anthem, it builds a sense of community and demonstrates The Travel Republic values that it is for the people."
