American author of childrens books. She is best known for creating the intermediate horse book series The Saddle Club, which was published from October 1988 until April 2001. The Saddle Club chronicled the adventures of thirteen-year-old Lisa Atwood and twelve-year-olds Stephanie Stevie Lake and Carole Hanson. The series was static in time; the girls never aged in 101 books, 7 special editions, and 3 Inside Stories.

Bonnie Bryant also wrote two spin-off series: Pony Tails, aimed at beginning readers, and Pine Hollow, aimed at teenage readers. The 16 Pony Tails books followed the lives of eight-year-olds May Grover, Corey Takamura, and Jasmine James. Pine Hollow featured Carole, Lisa, Stevie, and their new friends in a series set four years after The Saddle Club. Unlike The Saddle Club, Pine Hollow conformed to a realistic timeline. The 17 books took place over the span of less than a year. Later a television show called The Saddle Club, based on the books, was filmed in Australia.

Bonnie Bryant wrote at least 38 The Saddle Club books and 2 Pine Hollow books herself; after that they were taken over by a team of ghostwriters, a common practice in long-running childrens book series. Ghostwriters for the Saddle Club and Pine Hollow books included Caitlin Macy (sometimes credited as Caitlin C. Macy), Catherine Hapka, Sallie Bissell, Kimberly Brubaker Bradley, Helen Geraghty, Tina deVaron, Cat Johnston, Minna Jung, and Sheila Prescott-Vessey.

Bonnie Bryant is also the author of many novelizations of movies, including Teenage Mutant Ninja Turtles, The Karate Kid, and Honey, I Blew Up the Kid, written under her married name, B.B. Hiller.
