A cooler having a support bracket. The apparatus includes a cooler having a bottom, sidewalls and a lid, and a fastenerless support bracket. The fastenerless support bracket includes a cantilevered plate a primary stop adjacent to the inside of one of the sidewalls, the primary stop adapted to prevent the cantilevered plate from sliding in a first direction and a secondary stop adjacent to the upper portion of one of the sidewalls adapted to prevent the cantilevered plate from sliding in a second direction. The primary stop and the secondary stop are at a proximate portion of the cantilevered plate and adapted to be clamped between the lid and one of the sidewalls of the cooler. The cantilevered plate may be adapted to receive a fishing rod holder assembly attached to the distal end of the fastenerless support bracket.
