Hana no Ko Lunlun (花の子ルンルン, Hana no Ko Runrun), translated to English as The Flower Child Lunlun and Lulu, The Flower Angel, is a magical girl anime by Toei Animation, focusing on a theme of flowers in its stories. It was directed by Hiroshi Shidara and written by Shiro Jinbo. It was greatly successful in the West, particularly in Europe and in Latin America, as well as in Japan. An edited English-language dub of a few episodes titled Angel made this series one of, if not the first, magical girl anime works to reach the English-speaking market in the United States and Canada, well over a decade before Sailor Moon.

A theatrical short film, Hello Cherry Country (こんにちは桜の国, Konnichiwa Sakura no Kuni), was released in March 1980.

In 2009, William Winckler Productions produced two all-new English-dubbed movie versions edited from the original series titled Lun Lun the Flower Girl and Lun Lun the Flower Girl 2. Producer William Winckler, known for Tekkaman the Space Knight, wrote, produced and directed the English films, which are seen on broadband in Japan.

A Chinese-Japanese remake produced by Tencent Video and Toei Animation's Shanghai branch has been announced.
