Just Mercy: A Story of Justice and Redemption (2014) is a memoir by American attorney Bryan Stevenson that documents his career defending disadvantaged clients.

The book, focusing on injustices in the United States judicial system, alternates chapters between documenting Stevenson's efforts to overturn the wrongful conviction of Walter McMillian and his work on other cases, including children who receive life sentences, and other poor or marginalized clients.

To commemorate the film, "Movie Tie-In" editions were released for both versions of the memoir on 3 December 2019 by imprints of Penguin Random House.

[9] Stevenson pitched the idea for the memoir to Chris Jackson of Spiegel & Grau based on a TED talk he had given, and was signed immediately.

This case was explored during a 1992 60 Minutes episode,[12] and in the book Circumstantial Evidence: Death, Life, and Justice in a Southern Town (1995)[13] by journalist Pete Earley.

[9] The book is a memoir about Stevenson's career as a lawyer and his work for poor clients, largely focusing on his efforts to overturn the wrongful conviction of Walter McMillian for the murder of Ronda Morrison.

[14][15] Based largely on testimony from a police informant, McMillian was convicted and sentenced to death for the murder of Ronda Morrison, a young white woman, in Monroeville, Alabama (the hometown of writers Harper Lee, who wrote To Kill a Mockingbird, and Truman Capote).

[16] Stevenson concentrates on the injustices that occur in the United States' criminal justice system, which had the world's highest incarceration rate and population at the time of publication.

[17] Stevenson recounts his first meeting with a death-row inmate in 1983, when he was a law student and intern in Georgia for the Southern Prisoners Defense Committee.

[14] Stevenson documents his work for other marginalized clients, including efforts to overturn and ban mandatory life sentences without parole given to defendants convicted of crimes committed as juveniles.

[19] In 2020 Oprah Winfrey wrote: "When I wanted to deepen my understanding of mass incarceration and social justice, I was guided by Bryan Stevenson's masterful Just Mercy".

"[22] Tutu also wrote that the book "should be read by people of conscience in every civilized country in the world to discover what happens when revenge and retribution replace justice and mercy.

[24] Critic A. O. Scott wrote that it "is a painful, beautiful, revelatory book, the kind of reading experience that can permanently alter your understanding of the world.

[30] In his review, Ted Conover wrote that the memoir "aggregates and personalizes the struggle against injustice in the story of one activist lawyer" and that "[y]ou don't have to read too long to start cheering for this man".

[43] In December 2019, CNN included it in a list of the decade's '10 most influential books', noting that it "is a compelling portrait of a lawyer dedicated to exposing the inequities of the US criminal justice system" and that "Stevenson masterfully connects his own fight with the struggles of McMillian and a few of his other former clients and personalizes the nation's raging debate on racial injustice and criminal justice reform.

[57] Kirkus Reviews posted an article on the book saying it "is required reading, embracing the ideals that 'we all need mercy, we all need justice, and—perhaps—we all need some measure of unmerited grace.

[62] On August 7th 2023 the book was banned for "Teaching About Controversial Issues" " by Yorkville, Illinois Community School District 115 Board of Education, after a closed door meeting.

[36] The magazine published an article noting that, while it had sold fifty-four thousand print editions of the book since its release in 2014, the sales had been slow and steady so that it had not previously made it on any of the lists.
