Dr Hilda Margaret Turnbull (née Morcombe) (born 15 January 1942) is an Australian politician.
Turnbull was born in Perth, and was a general practitioner before entering politics.
Her victory followed the retirement of veteran Collie Labor MP Tom Jones.
She was the National Party spokesperson for Health, Community Services and Women's Interests from March 1989 until November 1992, and the Coalition Shadow Minister for Family and Youth from November 1992 to February 1993 after the National Party re-entered their coalition with the Liberal Party.
Turnbull was defeated by Labor candidate Mick Murray at the 2001 state election.
