Ruth Ryan Langan is an award-winning author of romance novels. She is a Romantic Times Career Achievement Award winner and has twice been nominated for Romantic Times Reviwers' Choice Awards, for Jade and Return of the Prodigal Son. She has spent much of her career writing historical romance novels for the Harlequin Historicals line of category romances. Many of her book are set in medieval times, while others are western romances. She has also written some contemporary romances, and often includes elements of suspense in her novels.
Langan began her writing career in secret. Her family discovered her writings when her children came home unexpectedly from school one day and found her writing. When Langan's husband was told of her hobby, he bought her an electric typewriter "because 'writers need tools'". Her first book was published by Silhouette Books in 1981 after an editor picked it out of their slush pile. After the first sale was completed, Langan got an agent.
Langan is a charter member of the Romance Writers of America. She has five children and lives with her husband in Michigan.
