An improved utility cart is presented which can be configured in various ways so as to allow it to be: used for hauling game or fishing supplies, used as a seat-backed chair, or conveniently backpacked over rough terrain. A preferred embodiment includes: (a) an opening-upward frame structure, (b) a pair of wheels rotatably attached beneath the frame, (c) a handle having an end that is pivotably connected at a point on the front portion of the frame, (d) a seat having an edge that is pivotably attached at a point of the top side of the frame, and (e) a seat brace with an end that is pivotably connected at a second point on the top side of the frame, wherein the seat and seat brace are positionable such that the front portion of the seat is extended to a position which is approximately perpendicular to the top side of the frame and an end of the seat brace is extended from the frame so as to detachably connect with a point on the bottom surface of the seat so as to detachably lock the seat into its extended, second position for serving as a seat when the cart's frame is leaned upwards and supported on its rear portion.
