Long Season (subtitled ...we are not four seasons) is the sixth studio album by Japanese band Fishmans, released on October 25, 1996 in Japan through Polydor Records. Regarded as a landmark of Japanese rock music, it consists of a single 35-minute composition based on the band's earlier single "Season".

The album initially achieved modest success within the Japanese alternative scene but remained relatively obscure internationally until the 2010s. Since then, it has received critical acclaim and notoriety within online media circles, with Paste ranking it as the seventh-greatest album of all time in 2024. Notably, Fishmans performed the entire Long Season album as one piece during their final live shows in December 1998. A recording of one of these performances was later included on the album "98.12.28 男達の別れ" ("98.12.28 Otokotachi no Wakare"), further cementing the album's legacy.
