John Ajvide Lindqvist (born 1968 in Blackeberg, Sweden) is a Swedish novelist and short stories author.

Lindqvist grew up in the Stockholm suburb of Blackeberg, and his debut novel Låt den rätte komma in (Let the Right One In), a romantic, social realistic vampire horror story published in 2004, enjoyed great success in Sweden and abroad. Hanteringen av odöda (Handling the Undead) was published in 2005 and involved the rising of zombies, or the "re-living", in the Stockholm area. In 2006, he released his third book Pappersväggar (Paper walls), a collection of horror short stories. In 2007, his story Tindalos was published as a serial in the Swedish newspaper Dagens Nyheter, and also published as a free audiobook through the newspaper's website, read by the author himself. His works are published by Ordfront and have been translated into many languages, including English, Bulgarian, German, Italian, Spanish, Norwegian, Danish, Polish, Czech, Dutch and Russian.

Before becoming a published writer, Lindqvist worked for twelve years as a magician and stand-up comedian. As a teenager, Lindqvist used to perform street magic for the tourists walking on Västerlånggatan in Stockholm.

Besides fiction he has also written the screenplay for Sveriges Television's drama series Kommissionen, a large part of the material to the television series Reuter & Skoog, as well as the screenplay for the film based on Let the Right One in. The production company Tre Vänner has bought the rights to Hanteringen av odöda and are planning to make a film.

Lindqvist is a devoted Morrissey fan. In interviews he has stated that his debut novel's Swedish name got its name from the Morrissey song "Let the Right One Slip In". Furthermore, he has stated that his first thoughts when told that "Let the Right One In" was to be translated into English was that he enjoyed the thought of Morrissey being able to read the book having the name which was borrowed from his song.
