A high visibility reflective lacrosse ball and related methods of forming the high visibility reflective lacrosse ball. The high visibility reflective lacrosse ball includes a high visibility exterior that is clearly distinguishable from a background environment and is easily picked up by both camera lenses and human eyesight. The high visibility lacrosse ball can include a plurality of spaced apart, retroreflective markers that reflect a directional beam of light toward a light source. The high visibility exterior can include an exterior coating or layer having a color selected as being highly visible and/or fluorescent. The retroreflective markers can be formed from a reflective adhesive film. The exterior coating can be cured such that the exterior coating is robust and resilient and is neither degraded nor removed during typical game play.
