Louis (22 January 1397 – 18 December 1415) was the eighth of twelve children of King Charles VI of France and Isabeau of Bavaria.

[1] He was their third son and the second to hold the titles Dauphin of Viennois and Duke of Guyenne, inheriting them in 1401, at the death of his older brother, Charles (1392–1401).

The infant was carried to the font by Duke Louis of Orléans, Pierre le Bègue de Villaines, and Countess Joan of Ligny.

[2] On 26 April 1403, Charles decreed that if Louis inherited the throne while still a minor, he would not be under the traditional regency, but the queen mother and the dukes of Orléans, Bourbon, Burgundy, and Berry would guide him.

On 30 January 1404, the king ordered the establishment of a household (hôtel) and treasury separate from Queen Isabeau's for the seven-year-old Louis.

[2] Although Louis's marriage contract had been signed before a great council of the realm on 5 May 1403, the duke of Orléans, who had hoped his daughter would marry the dauphin, absented himself.

He died 18 December 1415,[3] possibly of dysentery, as recorded by the monk chronicler Michel Pintoin of the Basilica of St Denis.

Louis appears as the Dauphin in William Shakespeare's Henry V. He has been represented in film by Max Adrian in 1944, Keith Drinkel in 1979, Michael Maloney in 1989, Edward Akrout in 2012, and most recently Robert Pattinson in The King (2019).
