Alain Blanchard (born 14th century, executed in Rouen in 1419) was a commander of the crossbowmen of Rouen during the Hundred Years' War.
He was active in the defence of the city during its siege by king Henry V of England. When the city capitulated on January 20, 1419 the English demanded that three notable inhabitants be surrendered to be decapitated. One of them was Alain Blanchard.
