Granny, whose full name is presented as Emma Webster, is a fictional character created by Friz Freleng, best known from the Looney Tunes and Merrie Melodies animated short films of the 1950s and 1960s.

At least until the mid-1950s, Granny is depicted as an elderly spinster who wears spectacles, a gray bun and a late 19th-century-like schoolmarm dress; other old fashioned characteristics include her mode of transportation (usually, a Ford Model T or a horse and buggy) and her inability to relate to present fads (such as her telling Tweety she's about to try on a new "bikini bathing suit", which turns out to be a full one-piece outfit from the turn-of-the-20th century).

[5] Subsequent appearances of a similar "granny" character included The Cagey Canary (1941), directed by Avery and Bob Clampett; Hiss and Make Up (1943), directed by Friz Freleng; and Hare Force (1944), featuring Bugs Bunny and Sylvester the dog (a one-off character distinct from the later Sylvester the cat).

In the 1953 short Hare Trimmed, she starred as a rich widow who was being fought over by two suitors, Yosemite Sam and Bugs Bunny (the latter out to thwart the former's evil plan to marry her and then get her money).

She has appeared as a professor at Acme Looniversity and the mentor and favorite teacher of Mary Melody in Tiny Toon Adventures (in the reboot series Tiny Toons Looniversity, she appears as the university's dean), a world-traveling detective in The Sylvester and Tweety Mysteries, and a timekeeper in Bugs Bunny and Taz Time Busters.

An episode of Loonatics Unleashed featured characters named Queen Grannicus (voiced by Candi Milo), the Royal Tweetums and Sylth Vester (the latter being a parody of Darth Vader).

In "Eligible Bachelors", it is revealed that during World War II, Granny/Emma was a member of the WAC and along with Tweety she stopped Nazi Colonel Frankenheimer from stealing the Eiffel Tower and various paintings from the Louvre.

During the flashback of her World War II adventure to Daffy, she appears as an attractive red-headed young woman in a WAC uniform.
