The Last Podcast on the Left is a weekly podcast on the Last Podcast Network featuring comedian and podcast host Ben Kissel, podcast producer and researcher Marcus Parks, and comedian and actor Henry Zebrowski, all of whom are longtime friends. Episodes have explored the topics of serial killers, conspiracy theories, UFO sightings, ghosts, and readings of fan-submitted creepypastas. The name is a reference to the 1972 horror movie The Last House on the Left.
Episodes explore real and imagined horror, with a typical runtime of one to two hours. The show releases two episodes weekly, a main episode and a side story episode.
The opening theme of the podcast features snippets from serial killers, such as Jeffrey Dahmer who utters the line, "That's when the cannibalism started." It also includes the line and subsequent advertisement transition "Rise from your grave!" uttered by Zeus from the Sega action game Altered Beast. The closing theme is Al Bowlly's "Midnight, the Stars and You", a reference to The Shining.
Several repeat characters are present on the podcast, primarily voiced by Zebrowski, such as "Detective Popcorn" (the semi-erotic food-focused incompetent police detective), Charles Ng (a notorious serial killer), "Terry the Gnome", and Minnie and Nannie Williams (victims of serial killer H. H. Holmes).
The podcast was launched in 2011.
In 2017, The Last Podcast on the Left received the People's Voice Webby in the Podcasts & Digital Audio (Comedy) category.
In 2018, they filmed their first live show at Thalia Hall in Chicago, IL. In 2019, they filmed their second live show in New Orleans, LA. The hosts have toured extensively in the US and internationally for live events.
On November 19, 2019, it was announced that the show was moving exclusively to Spotify for ad sponsored episodes.
In 2020, Houghton Mifflin Harcourt released The Last Book on the Left, written by Kissel, Parks, and Zebrowski, and illustrated by Tom Neely.
