"Which Side Are You On?" is a song written in 1931 by activist Florence Reece, who was the wife of Sam Reece, a union organizer for the United Mine Workers in Harlan County, Kentucky. In June 2026, CBS News included the song in its list of the 250 essential American songs of the past 250 years.

Background
In 1931, miners and mine owners in southeastern Kentucky were engaged in a labor struggle called the Harlan County War. In an attempt to intimidate the family of union leader Sam Reece, Sheriff J. H. Blair and his men, hired by the mining company, illegally entered Reece's home in search of him. Reece had been warned and escaped but his wife, Florence, and their children were in the house. That night, after the men had gone, Florence wrote the lyrics to "Which Side Are You On?" on a calendar that hung in their kitchen. She said she borrowed the melody from a traditional Baptist hymn, "Lay the Lily Low", though there are other iterations of the tune like the traditional ballad "Jack Monroe".
Reece supported a second wave of miner strikes circa 1973, as recounted in the documentary Harlan County, USA. She and others perform "Which Side Are You On?" in the documentary. Reece also recorded the song later in life; it can be heard on the album Coal Mining Women.
Recordings
Pete Seeger, collecting labor union songs, learned "Which Side Are You On" in 1940. The following year, it was recorded by the Almanac Singers in a version that gained a wide audience. Billy Bragg, Deacon Blue, Dropkick Murphys, Natalie Merchant, Ani DiFranco, Elvis Costello and Joan Baez, Rebel Diaz, Tom Morello, Panopticon, and S.G. Goodman have all recorded their own interpretations of the song.
The song is referred to by Bob Dylan in the song "Desolation Row". It was also the inspiration for the title of Alessandro Portelli's 2011 book on Harlan County's coal mining community.
