Mary Wimbush (19 March 1924 – 31 October 2005) was an English actress whose career spanned sixty years.

She played Julia Pargetter in BBC Radio 4's popular soap opera The Archers from 1992 until her death.

Her father was a schoolmaster and her mother had trained at RADA, but did not pursue a stage career, although the family enjoyed taking part in amateur dramatics.

In the 1980s she appeared in the Doctor Who spin-off K-9 and Company and D.H. Lawrence adaptation Sons and Lovers (both 1981), and in the early 1990s as Aunt Agatha in three series of Jeeves and Wooster, with Stephen Fry and Hugh Laurie.
