Marion Halligan was born and educated in Newcastle, New South Wales, and worked as a school teacher and freelance journalist before becoming a prolific writer in her forties. She moved to Canberra in the 1960s and her first published short story appeared in the Australian Women's Weekly in 1969. She married Graham Halligan and they had two children.

Her fiction books include: Self Possession (1987), The Living Hothouse (1988), The Hanged Man in the Garden (1989), Spider Cup (1990), Lovers' Knots: A Hundred-Year Novel (1992), The Worry Box (1993), Wishbone (1994), The Midwife's Daughters (1997), The Golden Dress (1998), The Fog Garden: A Novel (2001), The Point (2003) and The Apricot Colonel (2006).

Halligan has published numerous short stories, including those in her Collected Stories (1997), in Best Australian Stories 2003, and those in Out of the Picture (1995), commissioned by the National Library of Australia and structured around works in the library's Pictorial Collection. Her food and travel writing includes Eat My Words (1990), Cockles of the Heart (1996) and Taste of Memory (2004). She co-authored Those Women Who Go to Hotels with Lucy Frost in 1997.

She contributed writing on life in the 1970s for a Canberra Museum and Gallery exhibition, and also developed a play, Elastics (performed in 1987). She has curated a permanent exhibition for Newcastle Regional Museum, How shall we live?, and has written a series of restaurant performances entitled Gastronomica for the Melbourne Festival.

She was a member of Seven Writers - a group of seven Canberra-based writers whose work vividly portrayed life 'beneath the surface of Canberra' - and as part of this collective she contributed to Canberra Tales (1988), later reissued as The Division of Love (1996), an anthology of short stories about life in Canberra.
