Little My (original , literally: "Little Mu") is a character in the Moomin series of books by Tove Jansson. The character first appeared in the fourth book, The Exploits of Moominpappa (1950). She is a small, determined and fiercely independent Mymble. Little My is brash, aggressive, mischievous and disrespectful, but can also be a good friend when she wants to. She is the Mymble's daughter's younger sister. She was eventually adopted by the Moomin family. The name originated from the twelfth letter of the Greek alphabet: μ (mu) – transliterated as my and pronounced in Swedish. In the metric system, lowercase μ, meaning "one-millionth", represents the prefix micro-, from the Greek (), meaning "small". Personality Little My is a very abrasive person who almost always succeeds in persuading her listener or discussion partner. She is an unconventional debater who uses emotion and logic to win arguments. She typically makes a personal attack on the person she is having the discussion with or about, states her own undocumented conclusions, exaggerates her opponents' arguments to ridicule them, and uses nonverbal effects to show her opponent's inferiority.

Moominsummer Madness (Book 5) – In the fifth book, Little My has grown enough to take a more active part in the plot, though she is still small enough that Snufkin can carry her in his pocket. She is now in the care of her older sister, The Mymble's daughter, who tries unsuccessfully to teach her good behavior, but is separated from the others during the course of the plot and ends up being rescued by Snufkin, whom she accompanies for most of the rest of the book as he battles a rule-obsessed Park Keeper and ends up unwittingly "rescuing" a group of other children as well. Moominland Midwinter (Book 6) – Little My is the only character, apart from Moomintroll, who wakes from hibernation and gets to experience winter for the first time. Unlike him, she immediately
