The rain gutter diverter system comprises an outer enclosure, a diverter, a height adjuster, and a ground hose. The outer enclosure extends a downspout. The diverter, located within the outer enclosure, collects and diverts a portion of the rainwater passing through the outer enclosure to a hose aperture on the side of the outer enclosure. A height adjuster coupled to the hose aperture passes the rainwater down to ground level where it enters a ground hose. The ground hose disperses the rainwater along the length of the ground hose. A flipper valve at the top of the diverter allows a user to prevent the diversion of rainwater. A debris guard above the diverter prevents debris from entering the diverter.
