"Koi no Dance Site" (恋のダンスサイト,Koi no Dansu Saito?, Dance site of love) is the eighth single of the J-pop idol group Morning Musume, released on January 26, 2000 as an 8 cm CD. It sold a total of 1,229,970 copies making it their second highest selling single and a number-two hit on the Oricon Charts. In 2004, it was re-released as part of the Early Single Box and again in 2005 as a 12 cm CD. The song also makes an appearance in the Japanese Nintendo DS game Osu! Tatakae! Ouendan.
It is the only Morning Musume single to date to feature group members contributing to the instrumental backing track, as several of the members can be heard blowing police whistles during the song's choruses and closing moments.
