A cargo retainer for use with a vehicle includes a mat having a top side, a bottom side, a leading portion, a trailing portion, and an aperture for securing the trailing portion to the vehicle via a fastener. The cargo retainer includes a retention anchor configured to attach to the vehicle. The retention anchor has a top portion and a cleat portion such that the top portion is coupled with the leading portion of the mat. The cleat portion of the retention anchor extends away from the bottom side of the mat and is adapted to be inserted into and retained by a gap formed between a cargo area of the vehicle and either a tailgate of the vehicle or a bumper of the vehicle.
