At five years old, she is unlikely to have her own career anytime soon.
But that has not stopped Harper Beckham becoming a trademark.
According to intellectual property office records, Victoria Beckham has registered her daughter's name for use in a range of branded products, including make-up, toys and clothing.
The Harper Beckham trademark has also been registered for use in the entertainment industry should Harper wish to replicate her mother's career as a pop star.
Mrs Beckham has also signed up the names of sons Brooklyn, Romeo and Cruz to the UK's Intellectual Property Office and the EU-wide office.
It means the children are now officially part of Brand Beckham - David Beckham registered his name in 2000 while Victoria trademarked her name in 2002. Last night, an intellectual property expert said it was unprecedented to trademark a five-year-old's.
Oliver Bray, a partner at international law firm RPC, said the move was usually reserved for those who were already celebrities.
'It normally happens when your career is getting going and a lawyer says, "Let's get some protection in place",' he said. 'As opposed to the future-proofing which is what Victoria Beckham has done with her children.
'In order to give you more levers to control your image, a trademark is an obvious place to go and it might be that society is driving the Beckhams to use these levers to protect their children in this more manipulative world in which we live.
'But from another point of view, you could call it savvy and looking to the future. '
Mrs Beckham has registered her children for trademarks covering six classes of products and a class for ‘entertainment services’ should they wish to go into showbusiness.
The trademarks cover brands of cosmetics such as perfume, lip gloss and even anti-wrinkle creams, as well as books, umbrellas, music, clothing and children's dolls.
In 2000, the former England captain registered 'David Beckham' as a trademark, while 'Victoria Beckham' was trademarked in 2002 as the former Spice Girl embarked on a solo music career.
In recent years, the couple, worth around ￡500 million, have allowed their children to capitalise on the Beckham brand.
Brooklyn, their eldest child, is managed by his father's agent Simon Oliveira and has done a number of lucrative modelling shoots.
In 2014, his younger brother Romeo fronted Burberry's Christmas campaign having first started modelling for the luxury fashion house at the age of 10.
Last year, the youngest brother Cruz launched his pop career with the release of a charity Christmas single.
Brand expert Nigel Currie said the decision to trademark the children's names was a wise move.
He said: 'Obviously the Beckham name is worth something and they don't want someone trading off it and using it to create their own brand.'
