Ten sets of famous triplets:
- Annoyingly Cute Triplets Who Lived Upon the Hill (recurring villains on the television show Codename: Kids Next Door)
- Lil, Helen, and Kate Armstrong (first triplets admitted to Cambridge University)
- Leanna, Monica, and Joy Creel (actors, Parent Trap 3, and Parent Trap 4: Hawaiian Honeymoon)
- Leslie, Chandler, and Frank Jr. Jr. Buffay (surrogate children of Phoebe Buffay on Friends)
- Huey, Dewey, and Louie Duck (great-nephews of Scrooge McDuck)
- The Saunders triplets (played the infant Harry Potter in Harry Potter and the Sorcerer's Stone)
- Nicole, Erica and Jaclyn Dahm (Playboy Playmates)
- Garrett, Spencer and Mitchell Gray (actors, Days of Our Lives))
- Violette, Blanche, and Rose (title characters in the animated film Les Triplettes de Belleville)
- Ana, Teresa and Elena (title characters in Les Tres Bessones, a series of Catalan children's books and TV shows)
Today's list is for 
marinwood, and it was sort of a tricky one. There just aren't that many famous triplets out there. But at least I managed to work in another Scrooge McDuck reference.
