Alpine is a city on the northeastern edge of Utah County, Utah, United States. The population was 9,555 at the 2010 census. Alpine has been one of the many quickly-growing cities of Utah since the 1970s, and especially the 1990s. It is located on the slopes of the Wasatch Range north of Highland and American Fork. The west side of the city runs above the Wasatch Fault.

The area which would one day become Alpine was settled by William Wordsworth and several other homesteading families in the fall of 1850. The town was originally called Mountainville, and under the latter name settlement was first made in 1851. The city was renamed because the views from the elevated town site were compared to the Swiss Alps.

Alpine is located on State Route 74, just north of the city of Highland.

According to the United States Census Bureau, the city has a total area of 7.4 square miles (19.2 km2). None of that area is covered with water, although a number of small mountain streams run through the city on years with sufficient rainfall.

There are a number of mountain biking trails around the city that attract bikers from all over the state. There are also many trails and paths well suited for back-trail hiking along the mountains. The nearby American Fork Canyon offers camping, swimming and access to mountaineering regions around Mt. Timpanogos.

The hills surrounding Alpine have been affected by a number of brush fires in recent years, the most devastating of which was the Quail Fire, which consumed over 2200 acres on the north-east side of town in July of 2012. The area is serviced by the Lone Peak Fire Department and Lone Peak Police Force.
