AIC 23 (also known as Alice in Chains Twenty-Three) is a 2013 mockumentary by American rock band Alice in Chains to promote their fifth studio album, The Devil Put Dinosaurs Here. The screenplay was co-written by guitarist/vocalist Jerry Cantrell, director Peter Darley Miller, and actor W. Earl Brown. The video premiered on Funny or Die on April 3, 2013. The title is a spoof of Pearl Jam's documentary Pearl Jam Twenty (2011).

Snippets of songs from The Devil Put Dinosaurs Here are featured in the film, such as the first two singles, "Hollow" and "Stone", and two songs that had not been made available before the album was released: "Voices" and "Phantom Limb".
