路易十三（Louis XIII，1601年9月27日－1643年5月14日）法国波旁王朝国王（1610年－1643年在位）。是亨利四世的长子，生于枫丹白露。幼年由其母玛丽·德·美第奇摄政。1615年与同是孩子的西班牙公主奥地利的安妮结婚。路易十三亲自执政后与主要依赖红衣主教黎须留的帮助，开始了法国的专制统治（1627年拉罗歇尔之围的胜利是转捩点）。在其统治期间，欧洲爆发了一场决定性的争霸战争——三十年战争（1618年~1648年），即欧洲最强大的两个王朝——法国波旁王朝与伊比利和德意志的哈布斯堡王朝——之间的最后较量。最终法国取得胜利，结束了长达三个世纪的哈布斯堡王朝霸权，成为新的欧洲霸主。1643年5月14日因骑马落水引起的肺炎而去世。

Louis XIII (27 September 1601—14 May 1643) was a monarch of the House of Bourbon who ruled as King of France from 1610 to 1643 and King of Navarre (as Louis II) from 1610 to 1620, when the crown of Navarre was merged with the French crown.

Shortly before his ninth birthday, Louis became king of France and Navarre after his father Henry IV was assassinated. His mother, Marie de' Medici, acted as regent during his minority. Mismanagement of the kingdom and ceaseless political intrigues by Marie de' Medici and her Italian favourites led the young king to take power in 1617 by exiling his mother and executing her followers, including Concino Concini, the most influential Italian at the French court.
