L'Empereur (ランペルール, Ranperūru) is a turn-based strategy video game for the Nintendo Entertainment System released by the Koei company in 1989.

The player chooses from one of four scenarios (or loads a saved game) that starts off in different years. The earliest scenario has Napoleon as a Commander in Marseille in 1796, and historically has him poised for his invasion of Italy. The second scenario has Napoleon in St. Malo as Commander-in-Chief in 1798. The third scenario, arguably the easiest starting point, has Napoleon as First Consul of France in 1802. The final scenario, which has Napoleon as Emperor, starts in 1806, and in this mode the player can control Napoleon's siblings and stepson as well.
