The Wright Flyer III was the third powered aircraft built by the Wright Brothers.

Orville Wright first flew the original Flyer III on 23 June 1905. The Flyer III had a new airframe, but used the propulsion system from the Flyer II, and was essentially the same design and same performance as Flyers I and II.

When rebuilding the Flyer III after a severe crash on 14 July 1905, the Wrights made radical changes to the design. They almost doubled the size of the elevator and rudder and moved them about twice the distance from the wings. They added two fixed vertical vanes (called "blinkers") between the elevators, and gave the wings a very slight dihedral. They disconnected the rudder of the rebuilt Flyer III from the wing-warping control, and as in all future aircraft, placed it on a separate control handle.

On 5 October 1905, Wilbur flew 24 miles (38.9 km) in 39 minutes 23 seconds[1], longer than the total duration of all the flights of 1903 and 1904. Four days later, they wrote to the United States Secretary of War, offering to sell the world's first practical fixed-wing aircraft.

Disassembled on 7 November 1905, they refurbished it as the 1908 prototype flown at Kitty Hawk from 6 to 14 May 1908. These May 1908 flights in the reconfigured Flyer III served as a means for Wilbur and Orville to test the new controls and also the passenger- carrying abilities of the aircraft. On May 14, 1908 Wilbur was flying above the dunes at Kitty Hawk when he pulled a wrong lever and crashed into a sand dune. Only the front elevator was damaged but the brothers had to move on to newer aircraft. Flyer III was left in the hangar there at Kitty Hawk unrepaired. In 1911 the Berkshire Museum of Pittsfield, Massachusetts obtained parts of the disassembled airplane and the 1911 Wright glider, but never assembled or exhibited them. These parts of the 1905 airplane remained in Massachusetts for almost forty years until Orville requested its return in 1946 for its restoration as a central exhibit at Edward A. Deeds' Carillon Park in Dayton, Ohio. Some Kitty Hawk residents also possessed pieces of the 1905 airplane; Deeds and Orville also obtained many of these for the restoration. At the end of the 1947-1950 restoration process, restorers estimated that the 1905 aircraft retained between 60 and 85% of its original material. The 1905 airplane is now displayed in the Wright Brothers Aviation Center at Carillon Historical Park in Dayton, Ohio and is a component of Dayton Aviation Heritage National Historical Park. The restored 1905 Wright Flyer III is the only fixed-wing aircraft to be designated a National Historic Landmark.
