Polkadot Stingray is a Japanese rock band from Fukuoka, Japan signed under Universal Sigma. The band's members consist of Shizuku (guitar and vocals), Harushi Ejima (guitar), Yuki Uemura (bass), and Kazuma Mitsuyasu (drums).

In 2017, Polkadot Stingray released their first major-label extended play, Dai-Seigi, on April 26, with the leading track, "Electric Public". The extended play was recorded with Hiromi Hirohiro from Tricot and Igarashi from Hitorie on bass due to Uemura injuring his arm. In July, they went on their first nation-wide tour, stopping at six cities. On November 8, 2017, they released their first studio album, Zenchizennō. To promote the album, they embarked on their second nation-wide tour in 2018.

In February 2018, Polkadot Stingray announced that they were releasing the extended play Ichidaiji in May, with its leading track, "Ichidaiji", as the theme song to the live-action film adaptation of Missions of Love. In September 2018, Polkadot Stingray announced that the song "Himitsu" will be the theme song for the film Smartphone wo Otoshita Dake nano ni.

Polkadot Stingray performed the ending theme to the anime series Radiant with the song "Radiant".

With a charismatic, cult-leader-like presence and a sharp, rock-solid musical ensemble, the band gained rapid traction through social media, quickly becoming a viral sensation—a momentum that has continued to this day. Their tour tickets consistently sell out.

The band’s vocalist and guitarist, Shizuku—who comes from a background as a game creator—brings a deep, creative drive that extends well beyond music; she oversees everything from songwriting and composition to graphic design and video production. Her ability to create something from nothing has captivated a vast audience.
