Catherine Mayer (born 24 January 1961) is an American-born British author and journalist, and the co-founder and President of the former Women's Equality Party (WE) in the UK.

[1] She moved to Britain as a child when her father, the theatre historian David Mayer, came to research a book and later secured employment at Manchester University, where his students included Ben Elton and Rik Mayall.

[2][3] Mayer started her career at The Economist and has worked as a foreign correspondent at the German news weekly Focus.

Mayer's lawsuit prompted other journalists to seek legal advice about sexual discrimination[12] and ended with an "amicable resolution" in 2018.

[22] The book covers the benefits of gender equality and how it is being promoted in various countries,[22][23] and has been described as "a compelling feminist call to arms".

[24] Her memoir Good Grief, which incorporates letters written by her mother and covers the death of both women's husbands and the coronavirus pandemic, was published by HarperCollins in December 2020,[25][26] with an updated paperback edition in February 2022.

[27] Reviewing Good Grief in The Observer, Kate Kellaway called it "smart, upbeat and brimming with fortitude",[28] and those who also gave endorsements and praise included Kate Mosse, who described it as "a perfect book, specific and personal, but spot on about the universal nature of grief and how we grieve.
