Mrs. Wingo is Doug Funnie's multi-subject teacher at Bluffington Elementary. She is usually shown as sweet and sympathetic, but is strict when she needs to be. She has taught at Bluffington Elementary for such a long time that Mr. Dink is one of her former students. Evidenced by the episode Doug Meets RoboBone, Ms. Wingo also is a fan of The Beets. Mrs. Wingo only appeared in the final episode of the Disney incarnation.
- Mrs. Wingo is based on the real Mrs. Margarete Wingo, a wonderfully talented teacher who taught for many years at Maude Trevvett Elementary School in Henrico County, Virginia and whose students included Doug's creator, Jim Jinkins.
