bioRxiv (pronounced "bio-archive") is an open access preprint repository for the biological sciences co-founded by John Inglis and Richard Sever in November 2013. It was hosted by Cold Spring Harbor Laboratory (CSHL) until March 11, 2025, when ownership transferred to the newly formed non-profit openRxiv, dedicated to bioRxiv and medRxiv.

As preprints, papers hosted on bioRxiv are not peer-reviewed (though submissions may be undergoing peer review and peer reviews from other sources may be posted alongside preprints). However, all submissions undergo a basic scrutinization process, which includes safeguarding checks, an automated plagiarism screening and an assessment of appropriateness. Moreover, readers may post comments.

It has been measured that two thirds of the papers posted in bioRxiv are later published in peer-reviewed journals. BioRxiv, and its sister site, medRxiv, have been major sources for the dissemination of COVID-19 research.
