In 2019, Stiefvater was diagnosed with Addison's disease after she collapsed on a book tour. She has been very public about her health condition in the hope that it would raise awareness for others.

In 2019, Stiefvater wrote the pilot for a TV show of The Raven Cycle.

Stiefvater has been very open about sharing her techniques and methods when writing. She has a series of blog posts entitled "how i write" describing her different approaches and sharing advice. In 2018 and 2019, Maggie Stiefvater gave writing seminars entitled Portraits & Dreams: Writing with Maggie Stiefvater. It included a lecture and a Q&A. She gave this lecture in Edinburgh, New York City, Seattle, Austin, Los Angeles, Brooklyn, Toronto, and Vancouver.

Stiefvater was born in Harrisonburg, Virginia. She described herself as an "anxious child with many phobias." As a child, she wanted to be a fighter pilot and race-car driver and was a voracious reader who enjoyed writing. By age 16, she was submitting manuscripts to publishers. After being home-schooled from sixth grade on, Stiefvater attended Mary Washington College, graduating with a B.A. in history. By the time she had entered college, she had already written over 30 novels, including four thrillers about the Irish Republican Army, a historical blockade runner novel, and a high-fantasy novel about "impassioned enchanters fighting among civil unrest." At 16, she legally changed her first name from Heidi to Margaret. Her maiden name was Hummel. After graduating, she worked as a portrait artist, specializing in equestrian art. In 2016, she gave a TEDx Talk for NASA entitled "How Bad Teens Become Famous People", in which she reflects on her youth as a "Bad Teen" and how those years have impacted her.

Stiefvater also created a Tarot card deck, The Raven's Prophecy Tarot Cards in September of 2015.

In 2015, Stiefvater drove her Mitsubishi Lancer Evolution X in a race against fellow author John Green at the Princeton Speedway. Both their vehicles caught fire.

Stiefvater has frequently used her passion for vehicles to promote her novels. To promote the second book of The Raven Cycle, The Dream Thieves, Stiefvater spray-painted her own car. She later allowed fans to also spray-paint the vehicle at the book's launch in Kansas City on September 18th, 2013. She repeated this for another event in October of 2016, where she let fans paint her Mitsubishi Lancer Evolution X. In 2013 Stiefvater went rally racing in a race car printed with the cover of The Raven Boys.

In 2011, Stiefvater published The Scorpio Races, which received 5 starred reviews and was named a Michael L. Printz Award Honor Book.

It was reported in 2011 that David Katzenberg and Seth Grahame-Smith’s KatzSmith Productions would produce a film of Scorpio Races. New Line Cinema, in conjunction with Weed Road, optioned the film rights for The Raven Boys shortly before the book's release in September 2012.

Stiefvater published her first novel, Lament, in 2008. Before Lament had been released, she sold the rights to Ballad, the sequel to Lament, and to Shiver, the first book in the trilogy The Wolves of Mercy Falls. Shiver spent more than 40 weeks on The New York Times Best Seller list.
