Midway is a city in northwestern Wasatch County, Utah, United States. It is located in the Heber Valley, approximately 3 miles (4.8 km) west of Heber City and 28 miles (45 km) southeast of Salt Lake City, on the opposite side of the Wasatch Mountains. The population was 6,003 at the 2020 census.

The first known European-Americans to visit the area were members of a fur-trapping brigade led by Étienne Provost, a French-Canadian trapper, in 1824. This expedition explored the region, which was then known as Upper Provo, a name derived from the Provo River that flows through the valley. While these early visitors did not establish permanent settlements, their journey marked the beginning of exploration in the area.

In the mid-1850s, settlers began to push into the Heber Valley, encouraged by reports from loggers in the nearby mountains who noted the fertile land. Settlers of Utah Valley pushed the territorial government to create a road up the Provo Canyon, a proposal favored by territorial governor Brigham Young. In 1858, the construction of a road through Provo Canyon provided easier access to the valley, allowing for further settlement. Despite early attempts in 1855 and 1857, harsh winters forced settlers to temporarily abandon the area. Permanent settlement was only achieved in 1858-59, when settlers established several small communities in the valley, two of which were west of the Provo River. These were known as the "upper settlement" and "lower settlement" on the Snake Creek River. The upper settlement was also called Mound City, named for the nearby limestone formations.

In the 1860s, the upper and lower settlement merged to become Midway, so named because it was the site of Fort Midway, halfway between the two. Though local history claims Midway's creation was prompted by the Black Hawk War, a post office named Midway was in operation at least as early as 1864, before the Black Hawk War began. The site of Fort Midway is now the town square.

According to the United States Census Bureau, the city has a total area of 3.3 square miles (8.7 km²), all land. The region in which Midway sits is known as the Wasatch Back. Midway is bisected from north to south by Snake Creek, which includes the Midway Fish Hatchery just before the creek joins the middle section of the Provo River above Deer Creek Reservoir.

This climatic region is typified by large seasonal temperature differences, with warm to hot summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Midway has a humid continental climate, abbreviated "Dfb" on climate maps.

The Wasatch Fault runs underneath Midway, including the main fault line west of the town and the Bald Mountain Fault, which runs through the valley as well. Fault activity is responsible for some of the formations in the mountains around Midway, as well as the characteristic limestone ("potrock") mounds and the prevalence of hot springs in the area.

As of the 2020 census, Midway had a population of 6,003. The median age was 39.8 years. 30.2% of residents were under the age of 18 and 18.8% of residents were 65 years of age or older. For every 100 females there were 100.2 males, and for every 100 females age 18 and over there were 95.8 males age 18 and over.
