Dee Dee's Teacher is a character from the Cartoon Network original series, Dexter's Laboratory whose real name is never given. She first appeared in the episode "That Crazy Robot". She is voiced by Kat Cressida.


Dee Dee's teacher has short orange hair like Dee Dee's mother and wears glasses (similar to her brother's), two gold earrings, and red lipstick. She also wears a purple sweater and gray pants.


All that is known about her is that she appears to be very strict or firm, at least to Dee Dee.


That Crazy Robot

She immediately recognized that Dee Dee's guest in her classroom was a humanoid robot, and tells Dee Dee to try to keep him under control until the test is completed.

Project Dee Dee

Although she is not seen, her voice is once again heard asking her students to present their projects on propulsion. When Dee Dee presents hers (which has been heavily modified by Dexter), it causes the school to be launched into orbit, taking Dee Dee's teacher and most of the students with her. Afterwards, Dexter and Dee Dee fled over the border.



  • In the credits she is simply referred to as "Teacher".
