A urine collector for collecting urine from a user includes a collector, a top cover coupled on top of the collector, and a urine guider. The collector has a bottom wall and a surrounding wall upwardly extended therefrom to define a cavity. The top cover has a ring shape and defines a top side with a size adapted for covering a hip of the user, wherein the top side of the top cover is sloped downwardly from an outer peripheral edge to an inner peripheral edge thereof for guiding urine flowing into the collector. The urine guider is provided at a bottom portion of the collector for guiding urine at the urine guider within the cavity of the collector and then for guiding the urine to a container. The urine collector is light in weight, easy to use, and able to prevent the overflow of urine in the collector.
