Series Run Overview
When people ask when did Hawaii Five-O end, they are usually referring to the classic series that began in 1968 and became a long-running police procedural on CBS. The original show launched on September 20, 1968, and built a reputation for steady action, cross-over events, and a largely stable cast across its many seasons.
Over the course of its years on air, Hawaii Five-O established itself as a pop-culture fixture in the locale of Honolulu and beyond. It ran until the early 1980s, with its final season marking the end of an era for the original format. Below are the verified dates, season structure, and legacy points that clarify when the series wrapped and what followed.
Season Timeline and Finale Details
The original Hawaii Five-O produced 278 episodes over 12 television seasons. It maintained a fall-to-spring schedule for most years, with breaks for summer repeats. The series finale aired in April 1980, bringing the long-running crime drama to a close and setting the stage for later continuations and reboots.
Unlike shorter runs, the show’s multi-season arc allowed recurring characters and evolving cases to remain familiar to viewers. CBS scheduled episodes with an eye toward consistent viewership, which helped the program remain on the air long enough to build a lasting catalog of episodes.
Final Season Context
The final season reflected changes in scheduling and storytelling that often accompany later cycles of established police procedurals. Production timelines, cast departures, and evolving television standards all helped shape how the series concluded. By the time the last episodes aired, Hawaii Five-O had become a reliable evening fixture for many households.
Understanding the precise end date and context explains why reruns and syndication deals continued long after the original broadcasts ended. It also clarifies the difference between this version and the later reboot that revived the Five-O name for a new audience.
Notable Transition to Reboot
The conclusion of the original series created room for a reimagined version that would premiere more than two decades later. While the reboot adopted the same core premise, it introduced modern production values, updated casting, and contemporary policing themes. The contrast between the two eras illustrates how the name and concept remained recognizable across generations.

Post-Series Legacy and Reruns
After the original run ended, Hawaii Five-O remained in syndication for many years, which kept the show in front of new viewers. Local stations and cable networks found steady audiences for the classic episodes, and the series became a frequent presence on afternoon and evening blocks. This longevity distinguishes it from many shows of the same era that faded more quickly from public view.
The availability of the full catalog on home video and streaming platforms further extended its life. Fans could revisit favorite episodes or discover the series for the first time, often drawing comparisons to modern procedurals in tone, pacing, and case-of-the-week structure.
Distinguishing Original from Reboot
A common point of confusion is when Hawaii Five-O end in the context of the reboot, which began in 2010 and ran until 2020. Viewers sometimes conflate the two versions, but it is important to note that the original series wrapped in 1980, well before the reboot was conceived. The reboot was a separate production that adopted the same title and basic premise while creating its own continuity.
The reboot’s conclusion in 2020 marked the end of a different, distinct series. By clarifying dates and production timelines, it becomes easier to discuss each version on its own terms and avoid factual overlap in coverage, reviews, or recommendations.
