Louis de Pointe du Lac is a fictional character in Anne Rice's The Vampire Chronicles series.

His mother, sister and brother, Paul, live just outside New Orleans on one of their two indigo plantations, named Pointe du Lac after the family.

An example of this is an anguished comment recalled by Louis in his memoir, where he muses: "I was thinking how sublime friendship between Lestat and me might have been; how few impediments to it there would have been, and how much to be shared."

Louis, in a moment of weakness, feeds from a five-year-old orphan he finds in an abandoned house within the plague-ridden section of New Orleans.

Louis accepts his "family", taking the "maternal" role with Claudia and finding contentment in their townhouse at Rue Royale.

Louis burns down the Théâtre, killing the vampires there as revenge for Claudia's death and drifts through the world with the Theatre's former leader, Armand, whom he had fallen in love with.

In the events of The Queen Of The Damned, Louis and other vampires come together at Maharet's house in the Sonoma Compound to fight against Akasha.

Louis is one of the only vampires to refuse the powerful blood offered by Maharet and Lestat, preferring to gain strength with age.

It is noted by David Talbot that with this transfusion of blood Louis may have lost some of his humanity and become more vampiric in nature and has become almost equal to Lestat in power.

Louis appeared as the character in the short-lived Broadway show Lestat: The Musical composed by Elton John and Bernie Taupin, and was played by Jim Stanek.
