The Blind Pig is a music venue in Ann Arbor, Michigan. The club was established as a home for blues musicians, although today it books predominantly indie rock acts and local groups.

The Blind Pig opened in 1971. The partners renovated an old downtown Ann Arbor building and named the combined cafe/club after illegal after-hours gathering places, referred to by the slang term blind pig, another name for a speakeasy.
