Gregory Maguire is an American novelist and children's writer, born on June 9, 1954, in Albany.

Maguire's education took him through several institutions in the northeastern United States. He studied at the State University of New York, including its Albany campus, and also attended Tufts University. His time at the Simmons College Center for the Study of Children's Literature reflects the dual character of his writing career, which encompasses both adult fiction and work addressed to younger readers.

Writing in English, Maguire has worked across children's literature and adult fiction throughout his career as a novelist. His engagement with both forms places him among authors who move between audiences, shaping narratives that draw on the conventions and imaginative possibilities associated with each. The range of his output suggests a sustained commitment to storytelling that does not settle into a single register or readership.

Maguire is the author of Wicked. That novel stands as the most prominently documented work in his bibliography, and it exists alongside his ongoing work as a children's writer — a pairing that has characterized his career from the beginning. It is this movement between fiction for adults and fiction for younger audiences that serves as the most consistent thread running through his work as a novelist.
