The People of the State of California v. Orenthal James Simpson was a criminal trial in Los Angeles County Superior Court in which former National Football League (NFL) player, broadcaster and actor O. J. Simpson was tried and acquitted for the murders of his ex-wife Nicole Brown Simpson and her friend Ronald Goldman. The pair were stabbed to death outside Brown's condominium in the Brentwood neighborhood of Los Angeles on the night of June 12, 1994. The trial spanned eleven months, from the jury's swearing-in on November 9, 1994. Opening statements were made on January 24, 1995, and Simpson was acquitted of both counts of murder on October 3 of the same year, despite overwhelming forensic evidence against him. The trial came shortly after the 1992 Los Angeles riots, and it is agreed that, controversially, the defense capitalised on the anger among the citys African-American community towards police to convince the majority-Black jury to acquit Simpson. The trial is often characterized as the trial of the century because of its international publicity, and has been described as the "most publicized" criminal trial in human history.Following perfunctory questioning by police detectives, Simpson was formally charged with the murders on June 17 after investigators found a blood-stained glove on his property. After he did not turn himself in at the agreed time, he became the object of a low-speed pursuit in a white 1993 Ford Bronco SUV owned and driven by his friend Al Cowlings. TV stations interrupted coverage of the 1994 NBA Finals to broadcast live coverage of the pursuit, which was watched by an estimated 95 million people. The pursuit and Simpson's arrest later on the same day were among the most widely publicized events in American history.

Simpson was represented by a high-profile defense team, referred to as the "Dream Team", which was initially led by Robert Shapiro and subsequently directed by Johnnie Cochran. The team also included F. Lee Bailey, Alan Dershowitz, Robert Kardashian, Shawn Holley, Carl E. Douglas, and Gerald Uelmen. Barry Scheck and Peter Neufeld were two additional attorneys who specialized in DNA evidence. While Deputy District Attorneys Marcia Clark, William Hodgman, and Christopher Darden believed they had a strong case against Simpson, Cochran was able to convince the jury that there was reasonable doubt concerning the DNA evidence in this case, which was a relatively new form of evidence in trials at that time. The reasonable doubt theory included evidence that the blood sample had allegedly been mishandled by lab scientists and technicians, and there were questionable circumstances that surrounded other court exhibits. Cochran and the defense team also alleged other misconduct by the LAPD related to racism and incompetence, in particular actions and comments of Detective Mark Fuhrman.

The trial became historically significant because of the reaction to the verdict. Although the nation observed the same evidence presented at trial, a division along racial lines emerged in observers' opinions of the verdict, which the media dubbed the "racial gap". A poll of Los Angeles County residents showed that most African-Americans thought that justice had been served by the "not guilty" verdict, while the majority of Whites thought it was a racially motivated jury nullification by a mostly African-American jury. More recent polling shows the "gap" has narrowed since the trial, with over half of polled black respondents in 2013 stating they believed Simpson was guilty.After the trial, Goldman's father filed a civil suit against Simpson. On February 4, 1997, the jury unanimously found Simpson responsible for the deaths of both Goldman and Brown. The Goldman family was awarded compensatory and punitive damages totaling $33.5 million ($56.5 million in 2021 dollars), but have received only a small portion of that monetary figure. In 2000, Simpson left California for Florida, one of the few states where personal assets such as homes and pensions cannot be seized to cover liabilities that were incurred in other states.

Orenthal James Simpson (born July 9, 1947), nicknamed "the Juice", is an American former football running back, broadcaster, actor, and advertising spokesman. Once a popular figure with the U.S. public, he is now best known for being tried for the murders of his former wife, Nicole Brown Simpson, and her friend Ron Goldman. Simpson was initially acquitted of the murders in criminal court but was later found responsible for both deaths in a civil trial.

Simpson attended the University of Southern California (USC), where he played football for the USC Trojans and won the Heisman Trophy in 1968. He played professionally as a running back in the National Football League (NFL) for 11 seasons, primarily with the Buffalo Bills from 1969 to 1977. He also played for the San Francisco 49ers from 1978 to 1979. In 1973, he became the first NFL player to rush for more than 2,000 yards in a season. He holds the record for the single-season yards-per-game average, which stands at 143.1. He was the only player to rush for over 2,000 yards in the 14-game regular season NFL format. Simpson was inducted into the College Football Hall of Fame in 1983 and the Pro Football Hall of Fame in 1985. After retiring from football, he began new careers in acting and football broadcasting.

In 1994, Simpson was arrested and charged with the murders of his ex-wife, Nicole Brown Simpson, and her friend, Ron Goldman. He was acquitted by a jury after a lengthy and internationally publicized trial. The families of the victims subsequently filed a civil suit against him. A civil court awarded a $33.5 million judgment against him in 1997 for the victims' wrongful deaths. In 2000, Simpson moved to Miami, Florida to avoid paying on the liability judgment, which as of 2021 remained mostly unpaid.

In 2007, Simpson was arrested in Las Vegas, Nevada, and charged with the felonies of armed robbery and kidnapping. In 2008, he was convicted and sentenced to 33 years' imprisonment, with a minimum of nine years without parole. He served his sentence at the Lovelock Correctional Center near Lovelock, Nevada. Simpson was granted parole on July 20, 2017, which was the minimum sentence. He was eligible for release from prison on October 1, 2017, and was released on that date. On December 14, 2021, Simpson was granted early release from his parole by the Nevada Division of Parole and Probation.
