Blackrocks Brewery is a craft brewery in Marquette, Michigan, United States. Former pharmaceutical salesmen David Manson and Andy Langlois opened Blackrocks in 2010, taking the name from a local landmark. They originally brewed their products in the basement of a Victorian-style house and used the building's other two floors as a taproom.

By 2013, persistent demand for Blackrocks' beer led Manson and Langlois to add an outdoor patio and increase their brewing capacity. This included purchasing and converting a nearby former Coca-Cola bottling plant. In the early 2020s, they expanded the brewery's taproom into an adjacent property to double its available indoor area.

As of 2025, Blackrocks is the second-largest craft brewery in Michigan's Upper Peninsula. Their most popular beer is 51K, an American IPA.
