As of the 2020 census, the population was 2,486, making it the fourth-least populous county in Utah. Its county seat is Loa. Due to its remoteness and harsh terrain, settlements did not appear in the future Wayne County until the 1880s. By 1892, there was enough settlement and enough interest in a separate county, that Utah Territory passed an act to separate the east portion of Piute into a separate county. The county was named for Wayne County, Tennessee, itself named for Anthony Wayne. The county boundaries have remained unchanged since its creation.
