Maire-Ilon Wikland (née Pääbo; born 5 February 1930) is an Estonian-born Swedish artist and illustrator.

She was met by Astrid Lindgren, who had just finished writing the book Mio, my Son and who could see immediately that Wikland was able to "draw fairytales".

[citation needed] Wikland is the artist who has illustrated the greatest number of Lindgren's books: She has also provided the illustrations for many picture books by Lindgren and many other writers, including The Dragon with Red Eyes, I Want a Brother or Sister, That’s My Baby, Brenda Helps Grandmother, Simon Small Moves in, and The Borrowers.

In 2009 "Ilon's Wonderland", a gallery and theme centre for children and families based on her works and illustrations, was opened in Haapsalu.

Wikland was awarded the Illis quorum by the government of Sweden in 2002 for her "outstanding ability to bring environments and characters to life from her own and Astrid Lindgren's writings".
