Shelton is a city in Fairfield County, Connecticut, United States. The population was 40,869 at the 2020 United States Census. The city is part of the Naugatuck Valley Planning Region.

Shelton was settled by the English as part of the town of Stratford, Connecticut, in 1639. On May 15, 1656, the Court of the Colony of Connecticut in Hartford affirmed that the town of Stratford included all of the territory 12 miles (19 km) inland from Long Island Sound, between the Housatonic River and the Fairfield town line. In 1662, Stratford selectmen Lt. Joseph Judson, Captain Joseph Hawley and John Minor had secured all the written deeds of transfer from the Golden Hill Paugussett Indian Nation for this vast territory that comprises the present-day towns of Trumbull, Shelton and Monroe. Shelton was split off from Stratford in 1789, as Huntington (named for Samuel Huntington). The current name originated in a manufacturing village started in the 1860s named for the Shelton Company founded by Edward N. Shelton—also founder of Ousatonic Water Power Company. The rapidly growing borough of Shelton incorporated as a city in 1915 and was consolidated with the town of Huntington in 1919 establishing the present city of Shelton.

Shelton was the site of one of the largest arson fires in the United States history. It happened in 1975 when the Sponge Rubber Products plant (formerly owned by B.F. Goodrich) was set on fire. Charles Moeller, president of parent company Grand Sheet Metal Products, was acquitted of criminal charges, but in a suit under civil law (where preponderance of evidence suffices to establish a factual claim), a jury found in 1988 the insurer was entitled to disallow claims on the fire losses, based on the finding that the company's top officials arranged the fire to claim insurance money. Eight others were convicted or pleaded guilty.

The explosion that destroyed the Sponge Rubber Plant on Canal Street in 1975 marked the start of the decline of Shelton's industries. During the remainder of the 1970s and 1980s several firms that operated factories along the banks of the Housatonic River either went out of business or relocated to areas where labor and operating costs were cheaper. In 1995, Sikorsky Aircraft closed a plant off Bridgeport Avenue that manufactured electrical components for helicopters.

With the completion of Route 8, new office spaces and businesses were attracted to the town, due to its Fairfield County location coupled with low costs of doing business as opposed to places such as Stamford or Greenwich. Major firms such as Tetley Tea, TIE Communication, I.T.T., Black and Decker, Sikorsky Aircraft, Gama Aviation, Chesebrough-Pond's, Tetra-Pak, General Electric, and Bunker Ramo. Over 2,000,000 square feet (190,000 m) of corporate office space spread across 12 buildings was constructed by the R.D. Scinto corporation alone.

Efforts are underway to restore nineteenth-century industrial buildings in the downtown area; those that were beyond repair were demolished in the late 1990s and early 2000s and replaced with the Veteran's Memorial and a farmer's market. The 10-acre (40,000 m) Riverwalk Park next to the Veterans Memorial was created on the site of the former Sponge Rubber Plant. Other buildings along Howe Avenue, one of the city's main thoroughfares, have been restored, while developers have renovated two 19th-century factory buildings on Bridge Street, converting them into luxury condominiums. Several downtown streets have been reconstructed as part of a streetscape improvement project: sidewalks were reconstructed with brick and cobblestone, trees were planted, and some power lines were rerouted underground to improve the appearance of Shelton's central business district. In March 2008, Connecticut Governor M. Jodi Rell announced that after negotiations with State Senator Dan Debicella and State Representative Jason Perillo, state bond funds in the amount of $2 million would be directed toward additional infrastructure improvements.

In November 2007, a tree growing on Soundview Avenue in Shelton was selected and felled to be the Rockefeller Center Christmas tree.

On May 30, 2008, producers and staff for the upcoming movie All Good Things shot one scene on Canal St. in downtown Shelton. The scene was underneath the train trestle and involved one of the characters dragging a body and dumping it into the Housatonic River.

On July 31, 2009, a line of heavy thunderstorms with weak rotation spawned an EF1 tornado, which touched down with wind speeds between 95 and 105 miles per hour. According to WTNH, the most concentrated damage was along the Oronoque Trail, where many trees were blown down. There were no injuries or fatalities.

In November 2013, a tree located on Kazo Drive was picked to be the second Rockefeller Center Christmas tree from Shelton.

According to the United States Census Bureau, the city has a total area of 31.9 square miles (83 km), of which 30.6 square miles (79 km) is land and 1.4 square miles (3.6 km), or 4.26%, is water.

There are two State Assembly districts that cover Shelton. In 2007, Republican State Representative Jason Perillo of the 113th District took office. He won in a special election following the death of Richard O. Belden, who had represented the town for 32 years. Republican State Representative Ben McGorty of the 122nd District took office after winning a special election in 2014 following the death of previous State Representative Larry Miller.

At the federal level, Shelton is represented by Democratic U.S. Senators Richard Blumenthal and Chris Murphy in the United States Senate, along with the rest of the state. Representation of Shelton in the U.S. House of Representatives is split between the 3rd and 4th congressional districts, which are represented by Democratic U.S. Representatives Rosa DeLauro and Jim Himes, respectively. The boundary between the two congressional districts lies roughly along Route 8; Himes represents the portion of the city to the north and west of Route 8 while DeLauro represents sections of Shelton to the south and east.

Shelton is a Republican stronghold in presidential elections, as the city has voted for the GOP presidential nominee in every election since 1964 when Lyndon B. Johnson carried the municipality in his landslide election.

Shelton is one of the few municipalities in Connecticut with its own sheriff's department, the Shelton Sheriff's Department. The sheriff's department, which is distinct from the police department, is responsible for serving legal process within the city of Shelton. The Fairfield County Sheriff's Department had a similar role before it and all other county sheriffs in Connecticut were abolished in 2000. The Shelton Sheriff's Department is not a law enforcement agency. Members are political appointees and receive no salary and derive income from fees charged to serve legal papers. As of 2022 the head of the department is Sheriff Carl Sylvester.

The City of Shelton's goal is to preserve at least 15% of the land as permanently protected, locally controlled open space in the following three forms: City of Shelton Public Open Space properties, Privately owned farmland protected by the purchase of development rights, and properties held by the non-profit Shelton Land Conservation Trust. As of 2009, these forms of open space amount to 13% of the City and more than 2,700 acres (11 km). The City of Shelton owns close to 2,000 acres (8.1 km) of Public Open Space, Protected Farmland is 411 acres (1.66 km), and the Shelton Land Trust organization has preserved 364 acres (1.47 km).

There are over 15 miles (24 km) of hiking trails in Shelton, including a portion of the Paugussett "Blue Blazed" trail, part of an 800-mile (1,300 km) network of hiking trails throughout the state. There is opportunity for fishing, boating, geocaching and letterboxing, hiking, walking and biking. Dogs are welcomed when on leash. There is no hunting on city-owned open space, by ordinance.

Shelton Public Schools include Shelton High School for grades 9 through 12, Shelton Intermediate School for grades 7 and 8. Perry Hill School for grades 5 and 6, and five primary schools for pre-kindergarten through fourth grade, including Elizabeth Shelton Elementary, Mohegan Elementary School, Long Hill Elementary School, Booth Hill Elementary School, and Sunnyside Elementary School.

The City of Shelton is protected by the 246-member all-volunteer Shelton Fire Department, which consists of four fire companies (Echo Hose Hook & Ladder Co. 1, Huntington Co. 3, Pine Rock Co. 4, White Hills Co. 5) operating out of four fire stations located throughout the city. There is also a board of fire commissioners with a representative from each company.

There are two private golf courses in town Highland Golf Club of Shelton is located in the downtown Shelton area where it was founded in 1900. It is a 9-hole course (with 10 greens to allow alternating #2 and #11 where the tee shot goes over Perry Hill Road) in which an unknown original designer created difficult greens. The clubhouse's 1920s era structure still remains as the core to the current structure. Brownson Country Club is an 18-hole venue located in the Huntington section of Shelton. There is an annual competition between the clubs for the "Mayor's Trophy", alternating the venue each year. The 2009 Champion and holder of the Trophy is Highland.
