Molly Peacock (born Buffalo, New York 1947) is an American-Canadian poet, essayist, biographer and speaker, whose multi-genre work includes memoir, short fiction, and a one-woman show.

Peacock's latest book is Flower Diary: Mary Hiester Reid Paints, Travels, Marries & Opens a Door, a layered memoir and biography that examines the balancing act of female creativity and domesticity in the life of Mary Hiester Reid, a painter who produced over three hundred floral still lifes and landscapes.

"[1] As with The Paper Garden, this "lush and beautifully produced" [2] treatise also tracks Peacock's own marriage with the Joyce scholar Michael Groden.

[citation needed] Peacock is also the author/performer of a one-woman show in poems, "The Shimmering Verge" produced by Louise Fagan Productions, reviewed by Laura Weinert in the New York Times.

[4] "She can inhabit a moment with quiet intensity: in a haunting poem about an alcoholic father hovering over her, she fully enters her scene, gripping the folds of fabric around her as if they might swallow her alive."
