Winifred Waddell, MBE, (8 October 1884, Cumberland, England – 1972) was an English-born Australian botanist.

[2][3] Waddell was the eldest of four children, born in an area called Head's Nook.

She attended Carlisle High School for Girls, and won many prizes, including for mathematics and botany.

[6][7] "In all weathers you will find Miss Waddell peering round In odd places, on a disused railway line, in the middle of a racecourse, on the edge of an old gold mine in a lovely valley or in a creek bank for 'survivals'", noted one newspaper profile in 1954.

[8] She was awarded the Australian Natural History Medallion of the Field Naturalist Club of Victoria.
