The Southern Documentary Fund (SDF) is a nonprofit organization dedicated to supporting documentary filmmakers working in or on topics concerning the American South. Founded in 2002, the SDF provides various resources, including production and development grants, fiscal sponsorship, mentorship, and professional development opportunities. It also facilitates screenings, such as its "Fresh Docs" work-in-progress series and "SDF Presents" completed film showcases, sometimes in partnership with film festivals across the South. The organization prioritizes support for underrepresented voices and aims to connect Southern filmmakers to a broader documentary film community.
