Victor, Prince Napoléon, titular 3rd Prince of Montfort, was the Bonapartist pretender to the French throne from 1879 until his death in 1926. He was known as Napoléon V by those who supported his claim.

Bonapartism is the political ideology supervening from Napoleon Bonaparte and his followers and successors. The term was used to refer to people who hoped to restore the House of Bonaparte and its style of government. In this sense, a Bonapartiste was a person who either actively participated in or advocated for conservative, monarchist, and imperial political factions in 19th-century France.
