Shirahamazaka High School Chorus Club is a musical artist and performing entity created for the 2012 original anime television series Tari Tari, produced by P.A. Works. The group is presented as the in-universe choir club of Shirahamazaka High School, the fictional setting of the series. As a credited music artist, the chorus club is the performing name used for several insert songs and ending theme recordings featured throughout the anime.

The music for Tari Tari was composed and arranged by Shiro Hamaguchi, who served as the series music composer and contributed to the group's musical identity. The lyrics for the club's songs were provided by various writers, including riya and micco. The chorus club's recordings feature the five main voice actors from the series performing in-character as their respective roles: Asami Seto as Konatsu Miyamoto, Saori Hayami as Sawa Okita, Ayahi Takagaki as Wakana Sakai, Nobunaga Shimazaki as Taichi Tanaka, and Natsuki Hanae as Atsuhiro Maeda. The vocal arrangements typically involve soprano, alto, and tenor harmonies that reflect the ensemble nature of the fictional club.

Shirahamazaka High School Chorus Club is best known for its association with two principal songs from Tari Tari. Shiokaze no Harmony serves as the primary ending theme for the series, used in episodes 1, 3 through 5, and 7 through 12, with a special version appearing in episode 13. The song features lyrics by micco, composition by Mai Sugimori, and arrangement by Kazunori Watanabe. The single for Shiokaze no Harmony was released on August 8, 2012, and includes the B-side track Triple Smiley, also performed by the chorus club.

Kokoro no Senritsu is another significant song performed by the chorus club, used as an insert song in episode 2 and as an ending theme in episode 6. The song features lyrics by riya, with music composition and arrangement by Shiro Hamaguchi. A version credited specifically as the five-member version of the chorus club appears on the Tari Tari music album.

Additional recordings by Shirahamazaka High School Chorus Club include goin my way (Chorus Club Version) used as an insert song, and Reflectia (Chorus Version) credited to Shirahamazaka High School Music Club in episode 1. The group also performed the Shirahamazaka High School Anthem.

The artist appears on several music releases related to Tari Tari. The Tari Tari Music Album, titled Utattari, Kanadetari, was released on September 26, 2012, featuring multiple chorus club recordings including Kokoro no Senritsu and Reflectia. A best album titled Tari Tari Shirahamazaka High School Chorus (Sometimes Badminton) Club Best Album was released on March 25, 2020.

As an artist, Shirahamazaka High School Chorus Club exists solely within the context of Tari Tari and does not have a performance history independent of the anime. The group represents a blending of voice acting performance and musical recording, where the fictional identities of the characters serve as the performing artists. The chorus club has no confirmed music credits for any anime work outside of Tari Tari.
