Legal drama, also called courtroom drama, is a genre of film and television that generally focuses on narratives regarding legal practice and the justice system. The American Film Institute (AFI) defines "courtroom drama" as a genre of film in which a system of justice plays a critical role in the film's narrative. Legal dramas have also followed the lives of the fictional attorneys, defendants, plaintiffs, or other persons related to the practice of law present in television show or film. Legal drama is distinct from police crime drama or detective fiction, which typically focus on police officers or detectives investigating and solving crimes. The focal point of legal dramas, more often, are events occurring within a courtroom, but may include any phases of legal procedure, such as jury deliberations or work done at law firms. Some legal dramas fictionalize real cases which have been litigated, such as the play turned into a movie, Inherit the Wind fictionalizing the Scopes Monkey Trial. As a genre, the term "legal drama" is usually applied to television shows and films, whereas legal thrillers typically refer to novels and plays.

Legal dramas typically portray moral dilemmas that occur with the practice of the law or participating in the justice system, many of which mirrors dilemmas in real life. The American Bar Association Journal has interpreted the public's enjoyment of legal dramas occur because "stories about the legal system are laced with human vulnerability." Indeed, even though "there are no car chases [and]... [g]uns are never drawn", legal dramas retain strong followings because of their presentation of moral intrigue in a setting that actually reflects what occurs in the world.

Legal dramas may present stories of the miscarriages of justice, such as persons wrongly convicted of a crime they did not commit. At times, stories may involve the moral implications of police misconduct, such as placing or tampering with evidence, such as in the 1993 film In the Name of the Father. More often, legal dramas focus on the attorneys' point of view when faced with these difficulties. For instance, in The Practice, a television legal drama series revolving around a firm of criminal defense attorneys, a common theme presented is the difficulty of defending clients known or believed to be guilty.

Finally, many legal dramas present themes that reflect politicized issues. In the 1960 film, Inherit the Wind, the politicized issue portrayed was the legality of a Tennessee statute that made it unlawful to teach the theory of evolution in a public school. As laws and public policy opinions change, so do the themes presented in legal dramas. The 1992 film A Few Good Men explored the psychology of superior orders, e.g. excusing criminal actions because they were only committed from 'following orders'. The film Philadelphia (1993) addressed homophobia, and the discrimination and public fear of HIV/AIDs carriers. In 1996, The People vs. Larry Flynt portrays the early years of Hustler Magazine and issues of obscenity and freedom of speech. You Don't Know Jack (2010) is a fictional biographic film about Dr. Jack Kevorkian and the legal actions he faced as a result of providing euthanasia services to terminal patients. Racial injustice remains a common theme from as far back as To Kill a Mockingbird in 1962 to the 2017 film Marshall.

Legal drama in American film has an extensive history stemming from as early as the 1908 film, Falsely Accused! The 1950s and 1960s presented a number of legal drama films including, 12 Angry Men (1957), Witness for the Prosecution (1957), I Want to Live! (1958), Anatomy of a Murder (1959), The Young Philadelphians (1959), Compulsion (1959), Inherit the Wind (1960), Judgment at Nuremberg (1961), and To Kill a Mockingbird (1962). Arguably, 12 Angry Men and To Kill a Mockingbird stand as the cornerstones of early legal dramas, garnering extensive acclaim, recognition, and awards. Despite underwhelming box office performance, 12 Angry Men was nominated in three different categories at the 30th Academy Awards and appears on half of the AFI 100 Years... series lists of films, which celebrate the greatest films in American cinema. Likewise, To Kill a Mockingbird received even more acclaim, garnering three academy awards out of eight total nominations at the 35th Academy Awards, appears on seven of the AFI's ten lists celebrating the greatest films, including ranking as the best courtroom drama, and selected for preservation United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". Other countries also premiered legal dramas or courtrooms dramas in the early 1900s, such as the French silent film The Passion of Joan of Arc (1928).

Other legal drama films have not focused on even the practice of law, such as Paper Chase, a film presenting the difficulty and anxiety of entering law school.

Legal thriller films provide introspection into the life of a lawyer and legal professionals.

Within films, the central character is often engaged in professional work and experiences an obstacle that they have to overcome such as a client's case. The character confronts problems with their personal life and work, as it is under threat by the complex case, creating and series of action and courtroom battles.
