Armand Deperdussin (July 8, 1864, in Liège, Belgium – June 11, 1924, in Paris) was a French business owner and early leader in aviation. After working in the silk trade, he became interested in aviation in 1910 after seeing the successes of pilot Louis Blériot. He then started the company Société de Production des Aéroplanes Deperdussin.

In 1912, he purchased Champagne Airfield and built 30 workshops and other buildings, creating one of the first flying schools. He hired aircraft designer Louis Béchereau, who created monohull planes with streamlined shapes that improved speed and performance. With skilled workers and new technology, the company won many awards, including the Gordon Bennett Trophy in France in 1912. Pilot Jules Védrines became the first person to fly faster than 100 mph (169.6 km/h) during this event. In 1913, pilot Maurice Prévost flew at 200.8 km/h (124.8 mph).

The company faced financial problems in August 1913. In 1913, Deperdussin was accused of getting bank loans through dishonest means like lying or forging documents. He was not tried in court until 1917. On March 30, 1917, he was found guilty of stealing 32 million francs from his company. He was fined 1,000 francs and sentenced to five years in prison.

In 1914, the company was renamed Société Pour L'Aviation et ses Dérivés (SPAD) after Blériot Aéronautique took control. Deperdussin died by suicide in 1924.
