New Harmony is a town in northern Washington County, Utah, United States.

The town was originally settled as part of efforts to mine and refine iron in the area.

Settlers built a crude foundry in 1852, but abandoned it soon after due to transport and logistics issues.

According to the United States Census Bureau, the town has a total area of 0.4 square miles (1.0 km2), all land.
