James Paul Blaylock is an American fantasy author. He is noted for his distinctive style. He writes in a humorous way: His characters never walk, they clump along, or when someone complains (in a flying machine) that flight is impossible, the other characters agree and show him why he's right.

He was born in Long Beach, California; studied English at California State University, Fullerton, receiving an M.A. in 1974; and lives in Orange, California, teaching creative writing at Chapman University. Many of his books are set in Orange County, California, and can more specifically be termed "fabulism" — that is, fantastic things happen in our present-day world, rather than in traditional fantasy, where the setting is often some other world. His works have also been categorized as magic realism.

He and his friends Tim Powers and K.W. Jeter were mentored by Philip K. Dick. Along with Powers he invented the poet William Ashbless. Blaylock and Powers have often collaborated with each other on writing stories, including The Better Boy, On Pirates, and The William Ashbless Memorial Cookbook.

Blaylock is also currently director of the Creative Writing Conservatory at the Orange County High School of the Arts, where Powers is Writer in Residence.
