Caroline Emma Criado-Perez (born June 1984) is a British feminist, activist and journalist.
Her first national campaign, the Women's Room project, was for female experts to be better represented in the media.
She opposed the removal of the only woman from British banknotes (other than the Queen), leading to the Bank of England's swift announcement that the image of Jane Austen would appear on the £10 note by 2017.
That campaign led to sustained harassment on the social networking website Twitter of Criado-Perez and other women.
Twitter announced plans to improve its complaint procedures as a result.
Her most recent campaign was for a sculpture of a woman in Parliament Square; the statue of Millicent Fawcett was unveiled in April 2018, as part of the centenary celebrations of the winning of women's suffrage in the United Kingdom.
