Adrienne Maree Brown, often styled adrienne maree brown (born September 6, 1978), is a writer, activist and facilitator. From 2006 to 2010, she was executive director of the Ruckus Society. She also co-founded and directed the United States League of Young Voters.

Brown describes her thought as postnationalism, and others have described it as Black feminism or womanism. She also supports, among others, the Black Lives Matter and prison abolition movements.

Much of her work as a writer is based on the writings of science-fiction author Octavia E. Butler. Her first book, Emergent Strategy, was published in 2017. Other books include Pleasure Activism: The Politics of Feeling Good, published in 2019, and We Will Not Cancel Us, published in 2020.

Brown also runs podcasts and has released a music project. Additionally, she works as a doula.

Brown was born on September 6, 1978, in El Paso, Texas, to a mixed-race couple who met at Clemson University in South Carolina. She is the eldest of three children. Her father was in the military and she spent much of her childhood abroad in Germany (see United States military deployments), as well as in Georgia, New York, and California. As mixed-race children, Brown and her sisters experienced racism in school.

Brown attended Columbia University where she studied African American Studies, political science, and voice. She was at the university when Amadou Diallo was killed by police officers in 1999. She cites this time as being pivotal to the development of her political consciousness, especially regarding issues of policing and race. She identifies as pansexual and has recounted experiences with homophobia and sexual assault.

After graduating from Columbia, Brown began working with the Harm Reduction Coalition in Brooklyn, and served as a social justice facilitator at the Social Forum.

She moved to Detroit in 2009 after being invited to consult with Detroit Summer in 2006, and after dating Detroit-based rapper Invincible.
