The Basic Income Earth Network (BIEN; until 2004 Basic Income European Network) is a network of academics and activists interested in the idea of basic income. It serves as a link between individuals and groups committed to or interested in basic income, and fosters informed discussion on this topic throughout the world. BIEN's website defines a basic income as "a periodic cash payment unconditionally delivered to all on an individual basis, without means-test or work requirement."

Formed in 1986, BIEN held its first international conference in Louvain-la-Neuve in September of that year. It expanded its scope from Europe to the Earth in 2004. From 1988 BIEN published a paper newsletter three times per year; later replaced by an electronic NewsFlash Archived 2017-06-06 at the Wayback Machine, distributed first six and now twelve times per year. Since 2011, BIEN has sponsored a news website, called Basic Income News.
