The prison abolition movement seeks to reduce and eliminate prisons and the wider carceral system. The movement seeks to replace the punitive justice system with alternative modes of dealing with issues of harm and injustice, such as through practices of restorative or transformative justice. 
There are various tendencies within the prison abolition movement. These tendencies define themselves in various ways in distinction from prison reform, which is attempts to improve conditions in prisons. Some prison abolition advocates also seek reforms simultaneously, while others promote only for 'non-reformist reforms,' and others eschew reform altogether.
The prison abolition movement intersects with other movements, such as police abolition, decolonization, anarchism, socialism, and feminism, among many others.
