Steve McGarrett is a fictional character from Hawaii Five-O who serves as the leader of the Hawaii Five-O (5−0) crime task force. McGarrett was originally played by Jack Lord and also by Alex O'Loughlin in the remake. He is partner to Detective Danny "Danno" Williams.

In the original show, Steve McGarrett was portrayed by Jack Lord from 1968 to 1980. McGarrett was a former United States Navy officer and Detective Captain in the Honolulu Police Department who had been requested by Governor Paul Jameson to head the Five-O Task Force, a fictional equivalent of the state police. He was portrayed as a highly driven cop and workaholic, often staying at his office until midnight. It was said that he "only takes orders from the Governor and God – and occasionally even they have trouble".

McGarrett had a sister Mary Ann (Nancy Malone). Their father was murdered by criminals when they were young. It was revealed that this personal tragedy was what motivated McGarrett to become a police officer.

McGarrett was an alcoholic but stops drinking by season 11 for unexplained reasons. He drove a 1974 Mercury Marquis.

Australian actor Alex O'Loughlin portrays Steve McGarrett in the 2010 remake. The current incarnation bears some similarities to Jack Lord's character, such as their Navy Intelligence background and a long-standing nemesis in Wo Fat.

In the pilot episode, Lieutenant Commander Steven J. "Steve" McGarrett was in South Korea on a classified mission escorting wanted arms dealer Anton Hesse when he received a call via satellite phone from his father John and finds out that Anton's brother Victor was coincidentally holding John hostage on an unrelated matter. McGarrett's convoy was attacked by a helicopter of armed men trying to rescue Anton, resulting in Anton being killed. When Victor finds out, he shoots John point blank with the younger McGarrett still on the line. McGarrett returns to Hawaii to bury his father and is asked by Governor Jameson to set up a task force with "full immunity and means" to investigate and capture criminals such as the Hesse brothers. Despite his initial hesitation, he eventually agrees and transfers to the United States Navy Reserve. He then recruits Newark PD transfer, Detective Sergeant Danny "Danno" Williams, his father's former trainee Lieutenant Chin Ho Kelly and recent HPD Academy graduate Officer Kono Kalakaua. These four make up the original members of the "Governor's Task Force", later renamed "Five-0". When McGarrett assembles his task force, he partners with Williams.
