The present invention relates to a hybrid unmanned aerial vehicle capable of stably flying that easily maintains a position thereof, while minimizing interference of disturbance caused by cross wind when vertically flying, and improves flying stability when horizontally flying. The hybrid unmanned aerial vehicle includes a streamlined fuselage; main wings provided to both sides of the fuselage at a center; a bar-shaped rotor support crossing the main wings which is parallel with both sides on the basis of a traveling direction of the fuselage; a main rotor having a rotor provided to the rotor support to form a rotation shaft which is vertical to the ground, and generating a lifting force to lift the fuselage; a propel rotor unit having a rotor provided to a front surface of the fuselage to form a rotation shaft which is parallel to the ground, and generating a propelling force of the fuselage; a retractable fuselage provided to a rear side of the fuselage; and tail wings provided to the rear of the fuselage. When the vehicle vertically takes off and lands, the retractable fuselage is inserted into the fuselage to shorten the traveling length of the retractable fuselage and maintain a cross section of the tail wing in a straight shape, thereby generating stable lifting force. When the vehicle horizontally flies, the retractable fuselage is retracted from the fuselage to increase the traveling length of the retractable fuselage and modify the cross section of the tail wings in a V-shape, thereby improving a flying range.
