Langley (Lushootseed: sc̓q̓abac) is a city in Island County, Washington, United States. It sits at the south end of Whidbey Island, overlooking the Saratoga Passage. The city's population was 1,035 at the 2010 census, while the ZIP Code Tabulation Area (ZCTA) for Langley's post office had a population of 4,878. By the 2020 census, the population increased to 1,147 people. Langley proper only covers 0.8 square miles (2.1 km), but its ZCTA extends for 26.20 square miles (67.9 km).

Langley has been home to the Snohomish people since time immemorial. For centuries, people came to the site of Langley to camp during the summer months, and there was a village nearby at Sandy Point (Lushootseed: č̓əč̓ɬqs), which, as of 1792, was inhabited by about 200 people; however, the Snohomish were removed to the Tulalip Reservation in the late 1800s, and the village was abandoned. The modern settlement of Langley was founded in the 1890s by Jacob Anthes, and the town was incorporated in 1913.

Langley is served by South Whidbey Fire/Emergency Medical Services, the Langley Police Department, and South Whidbey School District #206; the school district offices are located there.

Indigenous peoples, namely the Snohomish people, have inhabited south Whidbey Island since time immemorial. Langley is known in the Lushootseed language as sc̓q̓abac, meaning "gooseberry bush."

The site of Langley was a camping spot used during clam harvesting in the summer months. Nearby, there was a village of the dəgʷasx̌abš, a Snohomish band, approximately one mile east of Langley on Sandy Point (Lushootseed: č̓əč̓ɬqs). This village had a large potlatch house, which brought visitors, even as distant as the Samish, during festivities.

For centuries, warfare was uncommon in Puget Sound, and mainly retaliatory in nature. The main dangers to the Snohomish at the time were the Haida and other Northwest Coast peoples, who traveled in large war canoes from the far north to raid and pillage along the southern coasts.

In the 18th and 19th centuries, smallpox epidemics rocked the Northwest Coast, killing 90 percent of the population. In 1792, the village at č̓əč̓ɬqs was seen by Joseph Whidbey, who noted that the population seemed to be about 200 people. Later, the village would be abandoned in the late 1800s after the removal of the Snohomish people to the Tulalip Reservation.

Langley was founded in the 1890s by Jacob Anthes, and was named for J.W. Langley of Seattle. In 1902, Anthes built a logger bunkhouse that still stands in the downtown core (now functioning as the South Whidbey Historical Society Museum). Langley was officially incorporated on February 26, 1913.

In the late 1900s, a number of 4H rabbits escaped their enclosures at the Island County Fair and went on to thrive as a large feral population initially residing around the county fairgrounds and later spreading throughout Langley and south Whidbey Island. In the 2010s the rabbits became a controversial issue in local politics, with citizens and groups advocating for public policy positions from removal and relocation to eradication. Some favored controlling the rabbit population using raptors, while others advocated for a more lenient position of community acceptance.

The Dog House was opened in 1908 as an elite gentlemen's club called "The Olympic Club". However, on opening night the founder realized that he didn't have enough money to pay the entertainers, so he left town with all the money. Over the years, the building has acted as host to many businesses.

During the Prohibition era, the building was host to underground boxing and wrestling matches which were illegal on the mainland.

When Prohibition ended, the club became a public bar, and operated as a restaurant and bar until its closure in 2008. The Clyde Theatre began in the top floor of this building.

The City of Langley operates under a mayor–council government. The mayor and city council members are elected for four-year terms. The city council enacts ordinances and resolutions, holds public hearings, receives citizen comments, authorizes payment of city funds, approves contracts, and creates committees and boards to assist in the operation of city government. The city council meets on the first and third Monday of each month in City Hall at 5:30pm. The mayor presides over council meetings and is responsible for the administration of city government.

The current mayor is Kennedy Horstman, who was elected in November 2023.

Langley is also served by a sewage treatment facility on Coles Road, operated by the city's Public Works Department.

Paull Schell, the former mayor of Seattle, was an influence on city politics in the 90s and 2000s, constructing the Inn at Langley.

In January 2009, the City of Langley transferred ownership of the Langley Marina to the Port of South Whidbey. The small boat harbor consists of 41 slips and 330 feet of linear moorage that can accommodate vessels up to 190 feet (57.6 meters).

Facilities include restrooms and showers, water and 110v 20, 30, 50, and 100 amp power at the docks, a floating pump out station, and a boat launch. No fuel is available.

Langley is in the South Whidbey School District, which has been in declining in attendance over the last two decades.

The first school constructed in Langley, the original Langley High School and later the Langley Middle School after the new High School was constructed – home of the Cougars – closed permanently in 2017 and is now managed by local nonprofits and companies. There are two time capsules buried next to the Middle School flagpole, the next one scheduled to be opened in the year 2055, buried in 2005.

The main building has been converted into an artistic community classroom, known as the South Whidbey Community Center.

The gym has been converted into a CrossFit studio. The football field and track and field area are still maintained by the Community Center, and the science building is now home to the Veteran's Resource Center of South Whidbey.

Whidbey Children's Theatre is housed in the former school auditorium.

The library is now home to the Whidbey Dance Theatre and the Island Dance Studio.

The high school, home of the Falcons, absorbed grades 7–8 with the closure of the middle school in 2017. In 2023, grade 6 joined the high school building, as well. Grades 6-12 are now housed at the high school.

The home of the Dolphins and the home of the Orcas, constructed next door to one another, downsized and have now been merged into a singular entity, still occupying some classrooms in both campuses. Grades K – 6 are housed at the elementary school campus.

The Langley Library is located in a historic building constructed in 1923. This 100-year old public library became a branch of the Sno-Isle Libraries system in 2010. The 3,600 sq ft (330 m) building was temporarily closed on 17 February 2024 for remodeling. The project estimated to cost $4 million envisages improvements to the accessibility and energy efficiency while retaining the period appearance. About 1,400 sq ft (130 m) will be added to the lower level. During the project execution of 9–12 months, the library is temporarily located in the South Whidbey Community Center.

Mystery Weekend is a yearly mystery game event occurring during the last weekend in February. A fake newspaper story is run in the South Whidbey Record or in a fake newspaper that can be purchased from the Visitor & Information Center, detailing the persons involved and instructing players to seek out characters played by local residents.

The Welcome the Whales Festival and parade is held at the beginning of April each year.

The Djangofest NW Music Festival is held in September each year. This five-day festival celebrates the Romani jazz style of Django Reinhardt, and features workshops, concerts, and impromptu jam sessions around town.
