"One Room Disco" (ワンルーム・ディスコ, Wan Rūmu Disuko) is the ninth major single by Japanese band Perfume.

Lyrically, One Room Disco is about the expectations and anxieties of a new life in a new town during spring, which is the season when one in Japan typically graduates, enters the workforce, or moves.

The music video begins with the three members standing in front of six red, white, and blue rooms.

Kashiyuka brings a stool for A-chan to sit on; Nocchi pushes a wheeled wall with a window.

[4] A spotlight shines on A-chan, holding a golden foil star, as city skyscraper cutouts are placed before her.
