Amelia Gentleman (born 1972) is a British journalist. She is a reporter for The Guardian.

Gentleman studied Russian and History at Wadham College, Oxford, before becoming a journalist.

For six months, Gentleman worked for The Guardian on the story of the Windrush scandal, the deportation of people originally from British colonies in the Caribbean, or elsewhere in the Commonwealth, who legally had a right of residence in the UK. The scandal broke in April 2018 and within weeks led to resignation of the Conservative Home Secretary, Amber Rudd.

Gentleman won the 2018 Paul Foot Award for her work on the Windrush story. She was also named as the Political Studies Association's journalist of the year for 2018, with Carole Cadwalladr, and as journalist of the year in the British Journalism Awards, 2018.
