Island Circle is a course featured in Ridge Racer 7 and Ridge Racer Slipstream, located in Midtown, Ridge State.

While this course is only 10 meters longer than Harborline 765, it feels somewhat short, mainly because this is a curvaceous course. A series of complex corners raise the course's difficulty level, with the other culprit being the fact that the track is very narrow and that some of the corners could be blind, which urges the player to be careful to achieve best lap times.
