Hyampom (Wintun: Xaayin-pom) is a census-designated place (CDP) in Trinity County, California, US.

Hyampom is at an elevation of 1,503 feet (458 m) in the Trinity Mountains. Its population is 241 as of the 2020 census, remaining the same from the 2010 census.

The name "Hyampom" is said to have derived from a Wintu language term xaayin-pom, meaning "peaceful place." Hyampom was home to the Whilkut, Chimariko, and Northern Wintun Native American tribes. The explorer Jedediah Strong Smith visited Hyampom in April 1828. The first non-native settler in the area was Hank Young who moved to Hyampom on January 12, 1855.

There are many small beaches and swimming holes along the wild and scenic river. [1] The small valley in the Trinity Mountains has a small landing strip, the South Fork Trinity River and Hayfork Creek. [2]

According to the United States Census Bureau, the CDP covers an area of 20.3 square miles (52.5 km), all of which is land.

This region experiences warm and dry summers, with no average monthly temperature above 71.6 °F. According to the Köppen climate classification system, Hyampom has a warm-summer Mediterranean climate, abbreviated "Csb" on climate maps. Despite the warm-summer classification, daily highs reach above 90 degrees Fahrenheit on almost all days in summer, but the marine-influenced night temperatures are almost always below 60 degrees and most often around 50. There is snow in the winter, but the elevation is too low for significant snowfall. The nearest large town, Hayfork, which is 700 feet above Hyampom at 2,200 feet, gets approximately 20 to 25 inches of snow per year, and the nearest comparable weather station, at Big Flat on the Trinity River, gets 6.7 inches per year. Precipitation totals around 40 to 45 inches a year.

The main industries for employment are tourism, winemaking, the local school, county road department, and a children's camp, the Bar 717 Ranch, which was founded by Grover Gates, whose family settled in Hyampom in 1901. In the 1970s, the community was home to the sawmill of Jack Beebe – the large teepee burner of the sawmill is still standing today. The mill employed a number of workers, with "camp"-style housing for the families. [3] Currently, there is a general store, a bar/hardware store, and a bar/grill servicing the town, as well as a vineyard and an antique store.
