Jill Sheila Tweedie (22 May 1936 – 12 November 1993) was a British feminist, writer and broadcaster.

Her light style and left-leaning politics captured the spirit of British feminism in the 1970s and 1980s.

In November 2005 she was one of only five women included in the Press Gazette's 40-strong gallery of most influential British journalists.

She was married three times, to the Hungarian Count Bela Cziraky, to Bob d'Ancona, and lastly, to journalist Alan Brien, her partner until her death from motor neurone disease in 1993.
