Disclosed herein are an apparatus and method for providing a contactless Graphical User Interface (GUI). The apparatus for providing a contactless GUI includes a basic information management unit, a pointer tracking unit, and a mouse event management unit. The basic information management unit receives finger image information, and generates basic pointer information for a mouse pointer service. The pointer tracking unit analyzes the finger image information based on the basic pointer information, and generates a mouse operation event by tracking a mouse operation in order to control a mouse pointer based on results of the analysis. The mouse event management unit analyzes the mouse operation event, and generates an operation message corresponding to the mouse operation. The pointer tracking unit tracks the mouse operation by calculating the movement distance of the tips of a thumb and an index finger based on the finger image information.
