Starhawk (born Miriam Simos on June 17, 1951) is an American writer, teacher, and activist. She is known as a theorist of feminist Neopaganism and ecofeminism. She is a columnist for Beliefnet.com and for On Faith, the Newsweek/Washington Post online forum on religion.

Starhawk's book The Spiral Dance (1979) was one of the main inspirations behind the Goddess movement. In 2012, she was listed in Watkins' Mind Body Spirit magazine as one of the 100 Most Spiritually Influential Living People.

Starhawk is also an author, activist, permaculture designer, and a prominent voice in modern Goddess religion and earth-based spirituality. She is the author or coauthor of thirteen books, including the classics The Spiral Dance and The Fifth Sacred Thing. Her latest is the fiction novel City of Refuge, the long-awaited sequel to The Fifth Sacred Thing.

Starhawk directs Earth Activist Training, teaching permaculture design grounded in spirit and with a focus on organizing and activism. "Social permaculture"—the conscious design of regenerative human systems—is a particular focus of hers.

She lives on Golden Rabbit Ranch in Western Sonoma County, CA, where she is developing a model of sustainable living.
