Love Live! Superstar!! (ラブライブ！スーパースター！！, Rabu Raibu! Sūpāsutā!!) is a Japanese multimedia project co-developed by Kadokawa Corporation, music label Lantis, and animation studio Sunrise, a division of Bandai Namco Filmworks. The project is the third major and fourth overall installment in the Love Live! franchise after Love Live! School Idol Project, and Love Live! Sunshine!!. Superstar initially revolves around five schoolgirls forming an idol group named Liella! as an extracurricular club activity. With each passing school year, the group makes a name for themselves and go on to recruit several other members.

An anime television series by Sunrise aired on NHK Educational TV from July to October 2021. A second season aired from July to October 2022, while a third season aired from October to December 2024.

The story is set in the Yuigaoka Private Girls High School (私立結ヶ丘女子高等学校, Shiritsu Yuigaoka Joshi Kōtō Gakkō) that lies between the Omotesando, Harajuku, and Aoyama neighborhoods of Tokyo. Originally set to be demolished, the school has instead recently reopened to accept new students. Within a school that has not made a name for itself, along with no history or accomplishments to speak of, Kanon Shibuya and four other first-year students discover the existence of "school idols", and for one reason or another eventually join the school idol club (with the group later being named "Liella!") in order to leave their mark on the newly reopened academy. As time progresses, Liella! gains popularity with the general public and prospective students, which leads to new members joining with each consecutive school year. The number of club members gradually rises from the founding 5 in its first year, 9 in its second year, and 11 in its third year.
