Stoneybrook General Hospital is the main hospital in Stoneybrook. This is where anyone goes who has a medical emergency in Stoneybook within the BSC series.

Claudia is taken here by ambulance after breaking her leg in book #19 . While in the hospital, she shares a room with a fourteen year old girl named Cathy who didn't have a lot of visitors.

Karen goes to the emergency room when she breaks her wrist in BSLS #2 Karen's Roller Skates.

The visiting rules are rather relaxed unless you are in intensive care. Anyone can come visit and they can stay as long as they want as long as they aren't disturbing anyone.

Kristy thinks the food is worse than cafeteria food and airplane food put together.

Mary Anne, Kristy, Claudia, and Mallory (along with many of the regular characters in the series) were born here.
