Nicki Greenberg is a writer and illustrator based in Melbourne, Australia.
Greenberg began publishing her work in 1990, when she was still a teenager, with a series of books whose illustrations were based around characters based on her fingerprints, including Thumbs and the Disappearing Rabbit and Indexia's Mixed-Up Spells.
She returned to publishing in the early 2000s, writing and illustrating her own work, but had great success with graphic translations of classic works The Great Gatsby (2007) and Hamlet (2010): the latter was joint winner of the 2011 Children's Book Council of the Year award for picture book of the year, and was shortlisted for both an Aurealis Award and an Australian Book Industry Award.
Greenberg's more recent work includes the Naughtiest Reindeer series and the illustrated children's book The Cursed First Term of Zelda Stitch.
In 2009, her work was included in an exhibition of comic art, Super Heroes and Schlemiels: Jews and Comic Art, at the Jewish Museum of Australia in Melbourne.
