Top 5 Must-Watch Documentaries of September 2026: Streaming on Netflix, HBO Max, and Beyond

As expected, true-crime content highlighted September’s offerings on various streaming platforms, but there were still a few delightful surprises that offered relief from the usual themes of crime and controversy. While perhaps not as strong as August’s selections, Netflix, HBO Max, Prime Video, and Peacock showcased impressive titles—some of which could potentially land on year-end best-of lists.

Standout documentaries from September include a celebratory look at diehard fans of The Office, an intriguing profile of an Australian breakdancer who captured the internet’s scorn, an NFL player’s life chronicled through decades of home videos, and a bizarre murder case that captivated amateur detectives. My personal favorite is a heart-wrenching true-crime series on Netflix that maintained a spot on the platform’s Top 10 for four weeks. Here are the top five documentaries and docuseries from September.
