New Fork is a ghost town in Sublette County, Wyoming, United States, near Boulder.

New Fork was established in 1888 by John Vible and Louis Broderson, Danish immigrants who had arrived in the United States in 1884.

By 1908 a small town had grown around the store, and in 1910 Vible built a dance hall, called The Valhalla.

Vible and Broderson's original store was a log cabin, selling supplies obtained in Evanston.

[2] The death of Vible and members of his family from diphtheria and scarlet fever in 1915 started a decline, exacerbated by the abandonment of the Lander cut-off.
