Hawaii Five-0 is a CBS police procedural that aired from 2010 to 2020, producing 10 seasons and 241 episodes. The series reboots the original 1968–1980 Hawaii Five-O and follows an elite Honolulu task force as they pursue organized crime, terrorism, and other threats to the islands. This guide clarifies exactly how many seasons the show ran, how episode totals break down by season, and how the series evolved in tone, cast, and story arcs over time.
Number of Seasons and Series Span
Hawaii Five-0 premiered on CBS in September 2010 and concluded in April 2020 after 10 seasons. The series aired across three distinct phases:
- Early seasons (1–6) focused on serialized arcs and the task force’s clashes with international crime networks.
- Middle seasons (7–8) balanced ongoing mysteries with deeper character work and procedural cases.
- Later seasons (9–10) condensed storytelling into tighter arcs as the show approached its planned and actual series finale.
Across its decade-long run, Hawaii Five-0 maintained a consistent identity as an action-driven ensemble drama set against a recognizable Hawaiian backdrop.

These collaborative episodes highlight the interconnected world of CBS’s universe while advancing Hawaii-based storytelling.
Why the Season Question Comes Up
Viewers often ask how many seasons Hawaii Five-0 has because the show’s frequent crossover events and decade-long run can blur perceived boundaries. Some may conflate it with the original Hawaii Five-O, which spanned 12 seasons, or assume the reboot followed a similar length. Others may be checking whether another season is planned after the conclusion in 2020. Understanding the show’s true season count clarifies its scope and helps set expectations for new and returning fans alike.

Hawaii Five-0 is available on multiple streaming platforms, and full seasons can be rented or purchased digitally. The series delivers a mix of case-of-the-week procedural episodes and serialized arcs focusing on themes of loyalty, justice, and duty. Fans who enjoy ensemble casts, sustained world-building, and steady action will find the 10-season run a substantial commitment with consistent payoffs, while new viewers can start from the beginning to experience the full character journey.
Final Notes on Length and Legacy
With 10 seasons and 241 episodes, Hawaii Five-0 represents a durable run in modern broadcast television that balances episodic content with long-form storytelling. Its conclusion in 2020 marks the end of an era for the franchise, but the series remains a touchstone for contemporary procedurals set in distinctive locations.
