Hanazuki: Full of Treasures (also known as Hanazuki), stylized using umlauts as Han̈azüki, is an American animated children’s web television series produced by Titmouse, Inc. for Allspark Animation, a division of Hasbro and later by Boulder Media, with Stephen Davis of Allspark and Chris Prynoski of Titmouse serving as executive producers. Made in conjunction with a line of Hanazuki toys, it is based on characters and concepts which were developed by Hanneke Metselaar and Niko Stumpo before Hasbro purchased them in 2010.

The series debuted on YouTube on January 12, 2017, and was produced in conjunction with a line of merchandise to be released later the same year, including a toyline and digital app. The series received praise from critics, drawing favorable comparisons to other animated series such as My Little Pony: Friendship Is Magic and Steven Universe for its storytelling, visual aesthetic, and darker undertones. As of May 2017, the series has amassed over 120 million views. It was renewed for a second season, and aired in March 2019. Titmouse announced a month before the season's debut that they ended production of the series, leaving it on a hiatus with only eight episodes and fifteen shorts languished in development hell, in order for Hasbro to find another studio to do the animation.The series made its American televised debut on December 1, 2018, airing on Discovery Family.
