Hacker Public Radio (also known as HPR) is a free culture and technology oriented podcast produced as a community collaboration since 2005. It originated in USA but has contributors from around the world.^[2][3] The community has a governance structure^[4] and maintains social media presences on Facebook, LinkedIn, Libera Chat,^[5] and Mastodon.^[6]

The subject matter is described as anything that may be of value to hackers or hobbyists.^[7] Many are on open-source and Linux-related topics,^[2] or on security-related topics,^[8][9] with others on seemingly unrelated topics such as wild-swimming.^[10][11] HPR has the most frequent output of any Linux-related podcast.^[2] There are also some long-running series by regular hosts^[3] and in-depth discussions spanning multiple episodes.^[12]

Shows are typically published every weekday,^[7] and this schedule is achieved by actively soliciting contributions from the audience.^[9][13]

Not all shows are considered family-friendly,^[2] and as the community does not do any content moderation,^[13] all shows are marked explicit.

The show is unique in being purely community-driven. Audio submissions from community members are published as shows. These submissions may have been captured in a variety of ways and submitted in multiple formats. Many have markdown or even multimedia format metadata associated with them, including transcripts.^[14] All submissions are licensed under Creative Commons. These are then processed by software written by the community,^[3] and released as Ogg, Speex and MP3 formats,^[2] with an entry in the episode guide on the community website.^[12]
