Grafton is a ghost town, just south of Zion National Park in Washington County, Utah, United States.

In 1866, when the outbreak of the Black Hawk War caused widespread fear of Indian attacks, the town was completely evacuated to Rockville.

[4] Continued severe flooding discouraged resettlement, and most of the population moved permanently to more accessible locations on the other side of the river.

The end of the town is usually traced to 1921, when the local branch of the Church of Jesus Christ of Latter-day Saints was discontinued.

A United Press news item dated May 23, 1946, stated that the town was purchased by movie producer Harry Sherman as a film location site.
