A utility cart with lock box which includes a fixed housing portion mounted to the top of a cart storage unit, and a rotating housing portion rotatably mounted to the fixed housing portion. The fixed housing portion includes spaced sidewalls joined to a clear see through arcuate back wall, and an open front. The rotating housing portion includes spaced sidewalls joined to a clear see through arcuate front wall, and an open back. The rotating housing portion is dimensioned such that it can be rotated rearwardly up and over the fixed housing to provide access to items stored in the fixed housing portion, or under the closed rotating housing portion. Alternatively the rotating housing can be rotated forwardly and downwardly to enclose all items in the lock box. The items located in the lock box are visible whether the box is opened or closed.
