The Frog Princess is a Russian fairy tale in which the frog is the bride, Vasilisa the Wise, whom Prince Ivan rescues from Koschei. In the Grimms' Frog King (1812), the frog is a prince, freed when a princess throws him at a wall. Disney's The Princess and the Frog (2009) draws on the Grimm tale and a 2002 novel.
The three titles sound almost the same, so search results and book lists often mix them up. We compared the Russian text in Afanasyev's collection, the Grimms' tale in an early English translation and the published history of the Disney film. Everything was checked on 13 October 2026.

Three frog stories in brief
The Frog Princess (Russia)
A tsar tells his three sons to shoot arrows and marry where they land. Ivan's arrow is caught by a frog in a swamp. The frog produces the finest bread and a silk carpet woven overnight, then arrives at the feast as Vasilisa the Wise, so beautiful that everyone marvels. Ivan burns her frog skin too soon, she flies away as a swan, and he must find her in Koschei's kingdom with the help of animals he spared.
Afanasyev's collection has three variants, Nos. 267–269; the heroine is named Vasilisa the Wise in No. 269. Folklorists file it under ATU 402, "The Animal Bride". Her profile: Vasilisa the Wise.
The Frog King, or Iron Henry (Germany)
A princess drops her golden ball into a well. A frog fetches it after she promises him friendship, a seat at her table and a place in her bed, and she runs off without keeping her word. The frog follows her home, and the king makes her keep her promise. When the frog asks to sleep in her bed, she throws him against the wall in a rage, and he turns into a prince.
The 1812 text doesn't say who cast the spell. In the Grimms' later editions, including the 1857 text used for Margaret Hunt's translation, the prince explains that a wicked witch had bewitched him. His servant, Faithful Henry, had three iron bands put around his heart when his master was cursed, and they burst for joy on the ride home. It is No. 1 in the Grimms' Children's and Household Tales (1812), type ATU 440.
The Princess and the Frog (Disney, 2009)
In 1926 New Orleans, Tiana works two waitress jobs to save for her own restaurant. Prince Naveen of Maldonia has been turned into a frog by Dr. Facilier, a voodoo sorcerer. Naveen takes Tiana for a princess and asks for a kiss, and she turns into a frog as well. With help from an alligator, a firefly named Ray and the priestess Mama Odie, they defeat Facilier. Tiana and Naveen marry, which makes her a real princess, and their kiss turns them back into humans.

Where Disney's version comes from
The film's history, as summarized on English Wikipedia, names two sources. One is the Grimm tale, which is read to young Tiana in the film. The other is E. D. Baker's novel The Frog Princess (Bloomsbury, 2002), in which Princess Emma kisses a frog prince named Eadric and becomes a frog herself. That twist is the one Disney kept. The film even went into production in July 2006 under the working title The Frog Princess, a name it shares with the Russian tale and with Baker's book. That shared name is an easy source of mix-ups. The Russian tale is not listed among the film's sources.
The kiss most people remember from The Frog Prince is also later than the Grimms. In their text the princess throws the frog against the wall. The Wikipedia article on the tale, citing folklorist Heidi Anne Heiner, says the kissing version seems to have started in English translations.
What each story can teach
These are themes you can draw from the stories, not official morals.
- The Frog Princess: don't judge by appearances, since Ivan's brothers mock him for marrying a frog and are proved wrong. It is also about patience: Vasilisa tells Ivan he should have waited a little longer, and his hurry costs them both. And kindness pays off, because the animals Ivan spares later save him.
- The Frog King: a promise counts even when you made it carelessly. Older kids may enjoy arguing about the ending, since the princess gets her prince right after losing her temper.
- The Princess and the Frog: work hard for your dream, and don't forget the people and the fun along the way. Tiana and Naveen each learn something from the other.
FAQ
Is The Princess and the Frog based on the Russian Frog Princess?
No. Disney's 2009 film adapts the Grimms' The Frog Prince and borrows its main twist from E. D. Baker's 2002 novel The Frog Princess, in which the princess turns into a frog after a kiss. The film's development history doesn't list the Russian tale. The film's working title, The Frog Princess, adds to the confusion.
Does the princess kiss the frog in the Grimm fairy tale?
No. In the Grimms' 1812 version, the princess is disgusted when the frog asks to sleep in her bed and throws him against the wall. That breaks the spell, and he becomes a prince (later editions add that a wicked witch had cast it). The kiss comes later: Wikipedia, citing folklorist Heidi Anne Heiner, traces it to English translations.
Who is the frog in the Russian Frog Princess?
The frog is the bride: Vasilisa the Wise, in Afanasyev's best-known variant (No. 269). She takes off her frog skin to complete the tsar's tasks and to dance at his feast. In another variant (No. 267) the frog bride is called Elena the Beautiful, and some films call her Vasilisa the Beautiful.
Is Tiana the same as Vasilisa?
No. Tiana is a Disney heroine from 1920s New Orleans who dreams of opening a restaurant. Vasilisa the Wise is a heroine of Russian folk tales, a princess under a frog spell whose husband must rescue her from Koschei. Both spend time as frogs, but their stories, families and villains are completely different.
Which frog story is best for a 4-year-old?
The Grimms' The Frog Prince is the shortest, and it has no villain on stage. Explain the wall throw simply: the princess was angry, and that broke the spell. In our view, the Russian Frog Princess suits children from about five. Watch the Disney film first yourself if your child is sensitive to shadowy villains or sad scenes.
