The Mineriads () were a series of protests and often violent altercations by Jiu Valley miners in Bucharest during the 1990s, particularly 1990–91. The term "Mineriad" is also used to refer to the most significant and violent of these encounters, which occurred June 13–15, 1990. During the 1990s, the Jiu Valley miners played in Romanian politics, and their protests reflected inter-political and societal struggles in post-Revolution Romania.
