Somerset is a home rule-class city in Pulaski County, Kentucky, United States. The city population was 11,924 according to the 2020 census. It is the seat of Pulaski County.

Somerset was first settled in 1798 by Thomas Hansford and received its name from Somerset County, New Jersey, where some of the early settlers had formerly lived. Somerset became the Pulaski County seat in 1801, and was incorporated as a city in 1887. A Civil War battle was fought in January 1862 at Mill Springs (now "Nancy") about 8 miles (13 km) west of Somerset, and a museum is at the site. A smaller battle was fought nearby at Dutton's Hill in 1863. In 1875 tracks for the Southern Railway were completed and Somerset saw a population growth and an increase in industry. In the late 1930s and early 1940s, library services were provided by the pack horse library. The completion of Lake Cumberland in 1950 transformed Somerset from a sleepy rural community into a recreation center.

The Center for Rural Development in Somerset was established in 1996. It is a 501c(3) nonprofit organization that describes its mission as follows: "to provide leadership that stimulates innovative and sustainable economic development solutions and a better way of life for the citizens we serve." The center's programs and services focus on public safety, arts & culture, leadership, and technology.

The city is located at the eastern end of Kentucky's Mississippian Plateau (or Pennyroyal Plateau); however, the micropolitan area extends eastward into the Appalachian Plateau (or Eastern Kentucky Coalfield), and northward to Kentucky's Outer Bluegrass region. Thus, the area shows variations in landforms and scenery.

Nearby Lake Cumberland is one of the largest man-made lakes in the world (101 miles in length, with an average depth of 85 feet (26 m) and a normal pool containing more than 2 trillion gallons of water). Somerset is also near Cumberland Falls and the Big South Fork National River and Recreation Area; its tourism industries are, in part, due to its scenic and varied landscape.

According to the United States Census Bureau, the city has a total area of 11.3 square miles (29 km), of which 11.3 square miles (29 km) is land and 0.09% is water.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters. According to the Köppen Climate Classification system, Somerset has a humid subtropical climate, abbreviated "Cfa" on climate maps.

The coldest month of the year is January with an average minimum temperature of 29.0 °F (−1.7 °C).

The major demographic differences between the city and the micropolitan area relate to income, housing composition and age. The micropolitan area, as compared to the incorporated city, is more suburban in flavor and has a younger housing stock, a higher income, and contains most of the area's school age population. Over the last 20 years, housing growth has occurred along the Fishing Creek tributary of Lake Cumberland, which lies just to the west of the City of Somerset, and along the main body of Lake Cumberland between the City of Burnside and Fishing Creek. Much of the Somerset area housing growth in the last 20 years is lake-oriented.

As of the census of 2000, there were 11,352 people, 4,831 households, and 2,845 families residing within the City of Somerset (proper). The population density for the city proper was 1,007.1 persons per square mile (388.8 persons/km). A karst valley occupies the south-central portion of the city, taking up about 25% of the land area; this valley is quasi-industrialized and also contains parks and recreational facilities; most of the population lies to the east and north of this valley in fairly compact residential neighborhoods that have a real population density of about 1,800 persons per square mile. There were 5,428 housing units at an average density of 481.5 per square mile (185.9/km). The racial makeup of the city was 94.16% White, 3.66% Black, 0.18% Native American, 0.71% Asian, 0.26% from other races, and 1.02% from two or more races. Hispanic or Latino of any race were 0.99% of the population.

There were 4,831 households, out of which 26.6% had children under the age of 18 living with them, 41.3% were married couples living together, 15.0% had a female householder with no husband present, and 41.1% were non-families. 37.8% of all households were made up of individuals, 18.4% had someone living alone who was 65 years of age or older. The average household size was 2.13 and the average family size was 2.80.

In the city proper, 20.6% were under the age of 18, 8.5% were in the age cohort from 18 to 24, 27.8% from 25 to 44, 21.7% from 45 to 64, and 21.4% who were 65 years of age or older. The median age was 40 years. For every 100 females, there were 82.5 males. For every 100 females age 18 and over, there were 78.5 males.

Tourism is important to Somerset, due to its proximity to Lake Cumberland. Lake Cumberland generated approximately $150 million in revenue each year as of 2013, though the industry has been greatly impacted in recent years by the U.S. Army Corps of Engineers' work on the Wolf Creek Dam. Since 2007, Lake Cumberland has been at low levels to facilitate the Corps work. The city holds the annual Master Musicians Festival. The Civil War Battle of Mill Springs took place in nearby Nancy. In November 2006, the Mill Springs Battlefield Visitor Center and Museum opened. Begun in 2001, Somernites Cruise is a monthly classic car show held the fourth weekend of the months April through October.

In 2006, a new 58-acre (230,000 m) medical park, called MedPark West, was finished near the Lake Cumberland Regional Hospital (LCRH). LCRH is one of the largest in the state. LCRH is a JCAHO-accredited hospital with 304 beds. A virtual online tour of the hospital is available. A ventilator care facility, Rockcastle Regional Hospital and Respiratory Care Center, is in adjoining Rockcastle County.

On June 26, 2012, Somerset city voters approved the sale of alcoholic beverages by a margin of 2,167 "Wet" votes to 1,464 "Dry" votes. This vote allows for packaged liquor and beer sales, and sales by the drink at restaurants and bars.

In 2014, a municipal-run filling station, the Somerset Fuel Center, was opened in response to persistently high local gas prices. "The price of gas will be based on an average regional price and will include a small markup to cover costs, the mayor said." In addition to serving local residents, it was hoped the station would encourage visits to nearby Lake Cumberland for fishing and boating.

Nearby Somerset, located off Highway 461, is the Valley Oak Technology Complex, an industrial center. Housed there are such companies as SafeAuto.

Major employers in the Somerset area include:

• Blackboard
• Hendrickson
• Prairie Farms Dairy
• Safe Auto Insurance Company

There are schools in the county, served by two main school systems – Somerset Independent and Pulaski County. Students living within the city limits typically fall under the Somerset Independent school district. The Pulaski County School System contains Pulaski County High School (PCHS) and Southwestern High School (SWHS), which was built in 1993 to alleviate overcrowding.

There are other smaller schools, including Tabernacle Christian Academy, Science Hill Independent, Somerset Christian School, and Saline Christian Academy. The three main high schools are Southwestern, Pulaski County, and Somerset. There is a local two-year college, Somerset Community College, part of the Kentucky Community and Technical College System (KCTCS). Somerset Community College offers one of the few Aviation Maintenance Technology programs (Airframe and Powerplant) in Kentucky.
