The Pittsburgh railroad strike of 1877 occurred in Pittsburgh, Pennsylvania, as part of the Great Railroad Strike of 1877. It was one of many incidents of strikes, labor unrest and violence in cities across the United States, including several in Pennsylvania. Other cities dealing with similar unrest included Philadelphia, Reading, Shamokin and Scranton. The incidents followed repeated reductions in wages and sometimes increases in workload by railroad companies, during a period of economic recession following the Panic of 1873.
