# List of Magnum P.I. (2018 TV series) episodes

Magnum P.I. is an American action and crime drama television series developed by Peter M. Lenkov and Eric Guggenheim for CBS. The program is a reboot of the 1980–1988 show of the same name, which was created by Donald P. Bellisario and Glen A. Larson. The series features Jay Hernandez in the titular role of Thomas Magnum, originally made famous by Tom Selleck. Magnum is a private investigator and former Navy SEAL who solves crimes in Hawaii. The remainder of the cast is made up of Perdita Weeks as Juliet Higgins (a role which was gender flipped from Jonathan Higgins in the original series), Zachary Knighton as Orvilee "Rick" Wright, Stephen Hill as Theodore "T.C." Calvin, Amy Hill as Kumu Tuileta, and Tim Kang as Honolulu Police Department Detective Gordon Katsumoto.
The first season premiered on September 24, 2018, and ran until April 1, 2019. A second season was split into two parts, with the first airing from September 27, 2019, to January 31, 2020, before continuing on April 10, 2020, and ultimately concluding on May 8, 2020. Season three was delayed as a result of the COVID-19 pandemic. As a result, it had a reduced episode count. It began broadcasting on December 4, 2020, and its finale aired on May 7, 2021. The penultimate season transmitted from October 1, 2021 – May 6, 2022. Despite Magnum P.I. being a top-25 rated series, CBS cancelled the show six days later as a cost-cutting measure. Following negotiations with the studio, NBC picked the program up for an additional 20 episodes to be split over two seasons. They later made the decision to market the order as a two-part fifth and final season rather than a 10-episode fifth and sixth seasons, so that the studio wouldn't have to pay the actors a higher salary, which would be required if it was called a sixth season. Part 1 was broadcast from February 19 to April 23, 2023. Two months later, NBC cancelled the series as the performers' contracts were set to expire and they were unsure when production would continue as a result of the 2023 Writers Guild of America strike. The second part began airing on October 4, 2023, and concluded with a two-hour finale on January 3, 2024.
Magnum P.I. shares a fictional universe with the 2010 reboot of Hawaii Five-O, and the 2016 reboot of MacGyver; Magnum P.I. had a crossover event with the former in 2020. The three shows are collectively referred to as the Lenkov-verse as they are all developed by Lenkov; Guggenheim was also a co-showrunner on Hawaii Five-0 from 2016 to 2018.
During the course of the series, 96 episodes of Magnum P.I. aired over five seasons, between September 24, 2018, and January 3, 2024.
