Rockport is a ghost town in a narrow part of Weber Valley at the mouth of Three Mile Canyon in Summit County, Utah, United States.

Located 4 miles (6.4 km) south of Wanship, it was inhabited for nearly a century before the creation of Rockport Reservoir, which covered almost the whole townsite.

Freezing winter temperatures and deep snow made life difficult, but the pioneers stayed,[1] building their own gristmill in 1863.

[2] In 1866, however, when the outbreak of the Black Hawk War caused widespread fear of Ute attacks, the colony was completely evacuated to Wanship.

Despite the protests of these families and the majority of Summit County voters in a 1952 special election,[5] the government purchased the entire valley[1] in preparation for the construction of the dam.
