A bicycle rear derailleur is basically provided with a base member, a movable member and a moving mechanism. The movable member pivotally supports a chain guide. The moving mechanism is coupled between the base member and the movable member so that the movable member is movable relative to the base member. The chain guide includes a first guide plate, a second guide plate, a guide pulley rotatably disposed between the first and second guide plates and a tension pulley rotatably disposed between the first and second guide plates. The first and second guide plates are releasably coupled together by a tool-less connection.
