American trial lawyer who gained international prominence with his skillful and controversial defense of O.J. Simpson (Simpson, O.J.), a football player and celebrity who was charged with a double murder in 1994.

In 1949 Cochran's family moved from Louisiana to California, where he later became one of only two dozen African American students at Los Angeles High School. He graduated from the University of California at Los Angeles (UCLA) in 1959 and later earned a law degree from Loyola Law School (1962). After working for two years as a prosecutor for the city of Los Angeles, Cochran pursued a private career. His clients included celebrities such as Michael Jackson and Tupac Shakur as well as minority victims of police brutality.

Cochran first gained national recognition in 1994 when he joined the legal team defending Simpson, who was accused of killing his ex-wife, Nicole Brown Simpson, and her friend Ronald Goldman. In the high-profile trial, Cochran demonstrated his skill at connecting with jurors and putting the prosecution and police on the defensive. His trial strategies included a demonstration of the sloppy practices and outright incompetence of the Los Angeles Police Department. Ultimately, the legal team won an acquittal for Simpson (in 1995) by suggesting that the police department was racist and that the former football star had been framed.

At the beginning of the 21st century, Cochran oversaw 10 law firms throughout the country. He took on the role of chairman of the Upper Manhattan Empowerment Zone, a publicly funded agency that sought economic development for the neighbourhoods of Harlem, Washington Heights, and Inwood. Known for his philanthropy, Cochran established the Johnnie L. Cochran, Sr., scholarship for African American men at UCLA. His memoir, Journey to Justice, was published in 1996.
