Thumbelina is a literary fairy tale written by Danish author Hans Christian Andersen first published by C. A. Reitzel on 16 December 1835 in Copenhagen, Denmark, with "The Naughty Boy" and "The Travelling Companion" in the second instalment of Fairy Tales Told for Children. Thumbelina is about a tiny girl and her adventures with marriage-minded toads, moles, and cockchafers. She successfully avoids their intentions before falling in love with a flower-fairy prince just her size.
Thumbelina is chiefly Andersen's invention, though he did take inspiration from tales of miniature people such as "Tom Thumb". Thumbelina was published as one of a series of seven fairy tales in 1835 which were not well received by the Danish critics who disliked their informal style and their lack of morals. One critic, however, applauded Thumbelina. The earliest English translation of Thumbelina is dated 1846. The tale has been adapted to various media including television drama and animated film.
