Amidst sharing news of the £10m contract to be the face of the FIFA World Cup and Qatar, the human rights organisation accused Beckham of failing to mention the country's discriminatory culture.
Currently, it is illegal for people to be gay in Qatar, while a male guardianship system forces women to gain approval from men to marry, study or travel. More directly, 37 workers have died while constructing the country's World Cup stadiums according to reports from The Guardian.
Amnesty International's UK branch claimed Beckham should be using his global status to call out these "appalling" issues instead of ignoring them.
"This is just the latest slick and positive video about Qatar that David Beckham has put his face to, and yet again there's no mention of the county's appalling human rights record," Felix Jakens, Amnesty International UK's head of priority campaigns, told MailOnline.
"Beckham's global fame and status are PR gold for Qatar's image, but he should be using that same unique profile to call on FIFA and the Qatari authorities to properly remedy the terrible abuses that tens of thousands of migrant workers have faced in building the infrastructure to deliver the World Cup."
While Beckham said football could be a force for good in Qatar, Jakens said it was good for their tourist industry, not human rights.
Judgment was swift and severe from the wider public too. On Twitter, many claimed his decision was unprincipled, selfish and "for the money".
David Challen, an ambassador for UK's National Centre For Domestic Violence, wrote: "Sportswashing is inherently wrong. Those who promote nations with horrific human rights records actively silence those who are discriminated against, harmed and killed, all for more money. Why does @UNICEF continue to support David Beckham making millions from promoting Qatar??"
Another person shared several images with the caption: "A tale of David Beckham's life lasting 7 short years, and £10 million quid." The pictures showed Beckham supporting LGBT rights on Instagram, a Wikipedia page about women and gay rights in Qatar and news about Beckham's multimillion-dollar deal.
British gay lifestyle magazine Attitude also called out Beckham for "performative allyship" earlier this year.
"David Beckham continues to keep his money just about as far as possible from where his mouth is when it comes to the LGBTQ community," the post read.
The FIFA World Cup will run from November 21 to December 18. This year will be the first it is hosted by an Arab country.
