Netflix has built a massive library of documentaries that feel less like traditional nonfiction and more like cinematic experiences that linger in your mind long after the credits roll. From inspiring human stories and emotionally devastating journeys to disturbing true events and completely unbelievable real-life moments, some of these documentaries have become among the most gripping content currently streaming.

With powerful storytelling, stunning visuals, and deeply compelling real-world portrayals, here are 10 of the best documentaries on Netflix that deserve a place on your watchlist.

Sr. is a deeply personal documentary about the relationship between Robert Downey Jr. and his father, Robert Downey Sr., who was a counterculture icon during the 1960s and 70s. Directed by Chris Smith, the film explores art and creative obsession, generational trauma, addiction, forgiveness, and mortality. The documentary portrays Robert Downey Sr. as a brilliant yet flawed artist who became hugely influential in underground cinema through Putney Swope. 

By the time the film was made, Robert Downey Sr. was battling Parkinson’s disease in the final chapter of his life, giving Sr. a deeply emotional and reflective atmosphere. What makes the documentary resonate so powerfully is the way Downey Jr. confronts the painful realities of their shared past. Yet rather than becoming a story consumed by bitterness, it evolves into a raw and intimate journey about understanding and forgiveness.

A massive group of superstar artists came together in a single night to record a charity single for famine relief in Africa, under the guidance of producer Quincy Jones and songwriters Michael Jackson and Lionel Richie. The music documentary The Greatest Night in Pop takes the audience straight into it, revisiting the most legendary studio session in pop history: the making of We Are the World in 1985.

The documentary captures a rare moment in modern music history when individuality temporarily dissolves into collective purpose, showing how the song 'We Are the World' was not just recorded, but built in real time through collaboration, tension, and vulnerability, as dozens of music icons learn, adjust, laugh, argue, and try to blend their voices into something unified despite their different artistic styles, which is what makes The Greatest Night in Pop a must-watch.

Aileen: Queen of the Serial K------is a true-crime documentary centered on Aileen Wuornos, one of the most infamous female serial killers in modern history, who was convicted of seven m------ committed in Florida between 1989 and 1990. The film revisits how she confessed to all the crimes, while her defense argued aspects of self-defense in several cases, helping reconstruct how her story unfolded and why it became such a cultural obsession.

Directed by Emily Turner, the documentary explores how her life story was shaped by instability, including a troubled childhood, homelessness, and years of surviving on the margins of society, and how these experiences contributed to the path that led to her crimes. Instead of presenting a simple “criminal profile,” the film explores how society constructs narratives around people labeled as “monsters,” with Wuornos’ morally complex story.

The documentary Marty: Life Is Short is a Netflix biographical film about comedian and actor Martin Short, directed by Lawrence Kasdan. It traces his five-decade career across television, film, theater, and sketch comedy. But it’s not just a career recap; the film also digs into his personal life, including his upbringing in Canada, his breakthrough through shows like SCTV and SNL, and his long-standing creative partnerships with figures like Steve Martin, Eugene Levy, and Catherine O’Hara.

It also reflects on major personal losses that shaped his life, including the deaths of his parents, his brother, and, later, his wife Nancy Dolman, along with more recent family tragedies. Through it all, it explores how he continued performing and surviving, making grief coexist with joy and comedy. Directed by a longtime friend, the documentary blends humor and vulnerability, using behind-the-scenes clips and home footage that make his career feel lived-in rather than curated.

The Mystery of Marilyn Monroe: The Unheard Tapes is built around interviews conducted by journalist Anthony Summers during his investigation into Marilyn Monroe’s demise, featuring voices from people who knew her personally. Alongside the mystery surrounding her final days, the documentary explores the dark side of fame, the loneliness hidden behind celebrity image, and the blurred line between truth, conspiracy, and myth.

Directed by Emma Cooper, the film examines the tragic death of Marilyn Monroe in 1962 through restored audio tapes rather than relying solely on modern interviews, giving it an eerie yet deeply intimate atmosphere. At its core, the documentary focuses on Monroe’s misunderstood intelligence and vulnerability, while also exploring the theories surrounding her alleged connections to powerful political figures such as John F. Kennedy and Robert F. Kennedy.

Directed by Ed Perkins, Tell Me Who I Am is a deeply unsettling and emotional documentary that follows the true story of identical twins Alex Lewis and Marcus Lewis, whose lives are permanently altered after Alex Lewis loses his memory in a motorcycle accident at the age of 18. When he wakes up in the hospital, the only person he trusts is his twin brother, Marcus Lewis, becoming completely dependent on him to be the sole narrator of his past. However, Marcus Lewis hides the horrors that they experienced growing up to protect his brother from those painful memories.

Years later, Alex Lewis discovers disturbing photographs while going through family belongings, leading him to question the reality of his made-up past. Eventually, during the making of Tell Me Who I Am, Marcus Lewis reveals the full truth, turning the documentary into something unbearably intimate and deeply personal, as though the audience is living through the emotional confrontation alongside them.

After the release of her memoir Becoming on November 13, 2018, Michelle Obama launched a book tour that initially covered major U.S. cities through December before expanding to additional North American and European dates in 2019. Directed by Nadia Hallgren, the documentary Becoming follows Michelle Obama on her tour as she reflects on her childhood on Chicago’s South Side, her relationship with Barack Obama, motherhood, and life in the public eye.

Throughout the film, Obama connects with young girls, students, and communities, and these conversations become the emotional heartbeat of the documentary, giving it a sense of warmth and accessibility. Rather than heavily focusing on political strategy, Becoming centers on human vulnerability and self-discovery. It also explores the pressures of being the first Black First Lady, while portraying Michelle Obama not as a distant political figure, but as someone deeply relatable and grounded in her personal journey.

Ever heard of a murder trial where the defense basically said "the devil did it"? That’s exactly the chilling hook behind The Devil on Trial, a true-crime documentary centered on Arne Cheyenne Johnson and the infamous 1981 Connecticut case where he was accused of killing his landlord. The story takes a strange turn when Johnson’s defense claims he was under demonic possession at the time of the crime, a claim pushed into the spotlight by paranormal investigators Ed Warren and Lorraine Warren, who are also featured in the film through archival footage and past interviews.

This case became one of the first in U.S. legal history where demonic possession was argued as a defense in court, making it both controversial and widely sensationalized. What makes the documentary stand out is how it doesn’t just retell the case, but pulls one into the tension between belief and skepticism, including interviews from Arne Cheyenne Johnson himself, David Glatzel, who was allegedly possessed by the devil in his childhood, and other entities involved in the case.

13th is a powerful documentary directed by Ava DuVernay that explores the history of racial inequality in the United States. The title references the Thirteenth Amendment to the United States Constitution, which abolished slavery in 1865, except as punishment for a crime, which became a loophole for systems that continued to oppress Black Americans long after slavery had officially ended.

The film moves through different eras of American history, including slavery, Jim Crow laws, the War on Drugs, mass incarceration, private prisons, and political fear campaigns. Through interviews with conservatives, activists, historians, politicians, and legal experts, 13th creates a wider conversation about justice, race, and power in America, becoming an important and thought-provoking watch for anyone wanting to understand systemic inequality on a deeper level. 

During a difficult and emotionally draining period in his life, South African filmmaker and diver Craig Foster begins free-diving every day in a cold underwater kelp forest near Cape Town, where he forms an extraordinary bond with a wild octopus. Directed by Pippa Ehrlich and James Reed, My Octopus Teacher follows Foster’s journey, turning it into a deeply emotional and immersive nature documentary. 

What makes the film so special is that it goes far beyond being just a wildlife documentary. It explores the idea that humans are not separate from nature, but deeply connected to it. What begins as a simple observation slowly evolves into an intimate relationship as Foster watches the octopus navigate her short yet intense life cycle. Over time, the octopus begins recognizing and interacting with him, creating moments that feel almost unreal in their closeness and emotional depth.
