Coxey's Army was a protest march by unemployed workers from the United States, led by Ohio businessman Jacob Coxey. They marched on Washington D.C. in 1894, the second year of a four-year economic depression that was the worst in United States history to that time.

The phrase Coxey's Army has also come to refer to a ragtag band, possibly due to an incident during the second march in 1914.
