"Rumble Fish" (stylized at "rumble fish") is Do As Infinity's fifth single, released in 2000. Originally, "Summer Days" was going to be used as the title track for the single but "Rumble Fish" was used for an unexplained reason according to the Do the A-side booklet, which also says that the single's jacket was shot in Taiwan during their visit in 2000.
This song was included in the band's compilation album Do the A-side.
