The Donut Legion is a comedy-mystery novel by American author Joe R. Lansdale.

The novel concerns a missing persons investigation centered on a Texas cult that claims knowledge of a flying saucer.

Lansdale has stated that his interest in and judgments of cults—including Pizzagate, QAnon, and Jim Jones—inspired the novel.

In a positive review, the Associated Press said "Lansdale's prose is tight, he has laced his highly entertaining story with sly humor, and he has populated it with a cast of quirky characters." Similarly, Gabino Iglesias of Locus called the novel a "master class" in "impeccable character development [with] a philosophical touch," and named it "one of Lansdale's best, most entertaining standalone novels."

Conversely, Kirkus criticized "the otherworldly aspects of the [novel's] mystery [as] seriously muddled, and the whodunit, which might better be labeled a whathappened, [as] seriously disappointing."

According to Lansdale, a sequel novel entitled The Midnight Stars is forthcoming.
