The Wright Vertical 4 was an American aircraft engine built by the Wright brothers in the very early years of powered flight. It was a liquid-cooled piston engine with four inline cylinders, mounted vertically. (Earlier Wright engines were mounted horizontally.) It generated about 30-40 hp from a displacement of 240 in3 and weighed about 160-180 lb. Developed by Orville Wright in 1906, the Vertical 4 was produced by the Wright Company until 1912 and was the most numerous engine they manufactured. Around a hundred Vertical 4 engines were built, according to a Wright test foreman.

The Vertical 4 powered most Wright aircraft during this period, including the Model A and Model B and variants built for the U.S. Army and Navy.

This engine was also built under license by Bariquand et Marre in France and by Neue Automobil-Gesellschaft in Germany.
