This is a list of characters that appear in The Magic School Bus original series books (1986–2021), The Magic School Bus television series (1994–97) and The Magic School Bus Rides Again (2017–2020). Main The school is known as Walkerville Elementary, named after the fictional town of Walkerville, where it is located. The classic series books --which were the books by Joanna Cole and Bruce Degen-- had a larger number of students in Ms. Frizzle's class (19 instead of 8). However, 11 characters were omitted in the TV series, the TV tie-in books (based with the TV series), and the video game series.

She makes flamboyant entrances to start the class, causing some to remark "How does she do that?".

She also loves to surprise the students and although she denies that she knows everything, she seems to never be in the dark about her students' activities. To Arnold, she is strange, but he and his friends still love and respect her. Some of Ms. Frizzle's ongoing catchphrases are, "Bus, do your stuff!", "Take chances, make mistakes, get messy!", "Hit it
