Jonathan Anthony Stroud is an author of fantasy books, mainly for children and youths.

Stroud grew up in St Albans where he enjoyed reading books, drawing pictures, and writing stories. Between the ages seven and nine he was often ill, so he spent most of his days in the hospital or in his bed at home. To escape boredom he would occupy himself with books and stories. After he completed his studies of English literature at the University of York, he worked in London as an editor for the Walker Books store. He worked with different types of books there and this soon led to the writing of his own books. During the 1990s, he started publishing his own works and quickly gained success.

In May 1999, Stroud published his first childrens novel, Buried Fire, which was the first of a line of fantasy/mythology childrens books.

Among his most prominent works are the bestselling Bartimaeus Trilogy. A special feature of these novels compared to others of their genre is that Stroud examines the stereotypes and ethics of the magician class and the enslaved demons. This is done by examining the perspective of the sarcastic and slightly egomaniacal djinni Bartimaeus. The books in this series are The Amulet of Samarkand, The Golems Eye, and Ptolemys Gate, his first books to be published in the United States.

Stroud lives in St Albans, Hertfordshire, with his two children, Isabelle and Arthur, and his wife Gina, an illustrator of childrens books.
