Thelma is a 2024 American comedy-drama film written, directed, and edited by Josh Margolin. The film stars June Squibb as a woman who falls victim to a phone scam, and sets out to find the perpetrators with the help of her grandson (Fred Hechinger) and friend (Richard Roundtree, in his final role). Clark Gregg, Parker Posey, and Malcolm McDowell also star.

Thelma premiered at the 2024 Sundance Film Festival on January 18, 2024, and was released in the United States by Magnolia Pictures on June 21, 2024. The film received positive reviews and was named one of the top ten independent films of 2024 by the National Board of Review.

Thelma Post is the actual name of Margolin's grandmother who was the target of a phone scam. In that case her family intervened before the scam was completed, but it inspired Margolin to write the screenplay. The real life Thelma Post is shown mid-credits sitting in a car and saying the lines from the final scene of the movie in which she discusses the gnarled roots.
