Officially, Elsa is the oldest Disney princess, or should that be Queen? And that's because, by the second film, she's the ripe old age of 24. Yes, 24 is the oldest Disney princess so far. With the youngest being Snow White, who is only 14, Anna is apparently 21 and Frozen 2, making them the oldest princesses and the oldest siblings in a film so far. Most of the princesses are 16, including Ariel. Marrata Aurora Moana and Mulan whilst Jasmine is 15 and Pocahontas and Rapunzel are 18. Tiana and Cinderella are both 19. and Bell is 17, so there you go, you now know how old all the Disney princesses are.
