Wrightwood is a census-designated place in San Bernardino County, California. It sits at an elevation of 6,208 feet (1,892 m). The population was 4,525 at the 2010 census, up from the population of 3,837 at the 2000 census. Wrightwood is located 77 miles (124 km) northeast of Los Angeles. It is on the Pacific Crest Trail.

Located in a pine-covered valley in the San Gabriel Mountains, the Wrightwood area was first developed as cattle ranches in the 19th century by Nathan and Truman Swarthout. Later, the main ranch, owned by Sumner Wright, was broken up into residential and commercial lots, and by the 1920s a community had taken root. Early ski enthusiasts discovered the north-facing slopes of the San Gabriels above the Swarthout Valley. Until 1937, the ski area, originally known as Big Pines, was part of a Los Angeles County park. After WWII, Big Pines opened their 1946–47 ski season with a new chairlift and the Sepp Benedikter Ski School (according to their ad in the February 1947 issue of Western Skiing magazine). Highways were built connecting to the major routes in the Cajon Pass, making Wrightwood accessible without serious mountain driving.

In 1934, on two separate occasions a black bear was shot and killed by a Wrightwood resident. J. Dale Gentry, chairman of the California Fish and Game Commission, applied pressure to file charges against the two men. One of the men, Clyde Steele, was found not guilty at trial; the charges were dropped against the other man.

The former vacation community is now home to over 4,000 full-time residents. Serrano High School in the neighboring community of Phelan opened in 1982; it also serves Wrightwood and the neighboring community of Piñon Hills.

In August 2016, part of Wrightwood's population was evacuated as part of mandatory evacuations of over 82,000 people in San Bernardino County due to the Blue Cut Fire. In September 2020, the Bobcat Fire caused evacuation warnings for the Wrightwood area as it raged across the San Gabriel Mountains. In September 2024, the Bridge Fire caused the entire town to be evacuated.

According to the United States Census Bureau, the CDP has a total area of 5.9 square miles (15 km), 99.94% of it land and 0.06% of it water. The climate is Mediterranean (Köppen Csb) influenced by its highland position. Summers are vastly moderated by the cooling down of the air at the higher elevation compared to the hot plains to its north and the San Bernardino Valley to the south, although share the similar dry features and a lack of summer thunderstorms. In winter, the Mediterranean tendencies of the more semi-arid lowland areas are exaggerated by orographic lift, causing precipitation comparable to areas much further north in California. However, due to the elevation, a lot of winter precipitation falls as snow. Even so, daytime highs in all months average above freezing, rendering snowpacks unstable and unreliable.
