Erstfeld is a municipality in the canton of Uri in Switzerland.

In 1962 a collection of four gold torques and three gold arm rings were discovered near Erstfeld. While the exact origin date is unknown, they are likely from the 4th century BC. The nearly pure gold rings were discovered under 9 meters (30 ft) of land slide debris. The rings show Celtic motifs and designs and display a high level of skill. While their purpose is unknown, one theory is that they were offerings made to celebrate safely crossing the Alps.

Erstfeld is first mentioned in 1258 as Ourzcvelt. In 1638, it was listed under the Latin name in Protocampis. In 1831, it was known as Hirschfelden.
