The scrotal support garment includes a fabric material that forms a cup to support a wearer's scrotal sack and contents thereof. The cup has a wide upper end that tapers to a narrow lower end. An elongated thong extends from the lower end of the cup. In one embodiment, the thong bifurcates to form left and right shoulder straps that are unitary members extending to opposite sides of the upper end of the cup. In another embodiment, the thong bifurcates to form a first portion of left and right shoulder straps. Elongated second portions of the left and right shoulder straps extend from opposite sides of the cup. The first and second portions are joined by adjustment straps or releasable fasteners, such as buckles, so that the length of the shoulder straps is adjustable.
