The Boys released 40 total episodes over its five seasons.
Each season contains eight episodes, producing a straightforward total of 5 × 8 = 40. The series began with its first season on Amazon Prime Video in 2019 and concluded with its fifth and final season in 2026. The regular eight-episode structure remained consistent across the complete run.
The episode total refers only to the main live-action series. It does not include related productions such as the animated anthology The Boys Presents: Diabolical, the promotional web series Seven on 7 with Cameron Coleman, or the spin-off Gen V. Counting those would mix separate programs into the total.
The first season premiered on July 26, 2019. Seasons two, three, and four followed in 2020, 2022, and 2024, respectively. The final season premiered in April 2026 and ended on May 20, 2026, bringing the main series to episode 40.
Viewers sometimes remember 32 episodes because the first four seasons contained 32 episodes altogether. That figure was correct before the eight-episode fifth season was released, but it is no longer the full-series total.
