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

By 2013, persistent high demand for Blackrocks' beer led Manson and Langlois to add an outdoor patio and increase their brewing capacity. This included the purchase and conversion of 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 2024^[update], Blackrocks is the largest craft brewery in Michigan's Upper Peninsula. Their most popular beer is 51K, an American IPA.
