LibriVox is a group of worldwide volunteers who read and record public domain texts, creating free public domain audiobooks for download from their website and other digital library hosting sites on the internet. It was founded in 2005 by Hugh McGuire with the objective to "make all books in the public domain available, for free, in audio format on the internet."

On 6 August 2016, the completed projects numbered 10,000; on 14 February 2021 there were 15,000, and on 17 December 2024 the catalog reached 20,000 recordings. Most releases are in the English language, but many non-English works are also available. There are multiple affiliated projects that are providing additional content. LibriVox is associated with Project Gutenberg from where the project gets some of its texts, and the Internet Archive that hosts digital recordings.

All LibriVox recordings are in the Public Domain.
