A folding utility cart including a rectangular floor panel, a pair of side walls hinged along respective side edges of the floor panel for pivotal movement between vertical erected positions and horizontal, generally prone positions atop the floor panel, and a pair of opposed side wheels journaled relative to the respective side walls. Front and rear end wall panels are slidably received between respective ends of the side walls in their erected positions, and said front and rear end panels each include a pair of oppositely laterally extended top edge projections including downwardly extended fixed pins to engage through holes in top rail portions of the side walls to securely lock the side, front and rear walls in fully erected positions. At their rear ends, the side wall top rails include sleeve sockets to slidably receive the respective ends of a generally U-shaped handle, and the rear pin holes extend through the sleeves and handle ends in a manner whereby the rear wall pins serve to lock the handle in place when the rear wall is properly engaged between the side wall rear ends in their erected positions. Downwardly projecting lugs from the bottom edges of the front and rear walls respectively engage front and rear edge portions of the floor panel.
