Mendocino County (pronounced men-duh-SEE-noh) is a county located on the North Coast of California. In 2020, about 91,601 people lived here. The main city and government center is Ukiah.
Mendocino County is special because it's located between the San Francisco Bay Area and the California/Oregon border. It's separated from the Sacramento Valley by the California Coast Ranges. This county is also part of the Pacific temperate rainforests ecoregion, which is the largest temperate rainforest area on Earth.
You can find the famous "Skunk Train" here. It used to connect Fort Bragg with Willits using a steam train. Mendocino is also one of three counties in Northern California known as the "Emerald Triangle", along with Humboldt and Trinity counties.

History of Mendocino County
Mendocino County was one of the first counties in California. It was created in 1850 when California became a state. At first, not many American settlers lived here. So, it was managed by Sonoma County until 1859. Some of its land was even given to Sonoma County between 1850 and 1860.
How Mendocino Got Its Name
The county's name comes from Cape Mendocino. This cape was likely named after Antonio de Mendoza. He was a important leader (Viceroy) of New Spain from 1535 to 1542. He sent an expedition to this coast in 1542. Another possible namesake is Lorenzo Suárez de Mendoza, who was a Viceroy from 1580 to 1583. The word Mendocino is a form of the family name Mendoza.
Spanish and Mexican influence didn't reach far into Mendocino County. Only two Mexican land grants were made in the southern part. These were Rancho Sanel in Hopland in 1844 and Rancho Yokaya in the Ukiah Valley in 1845.
Native American History in Mendocino
In the 1800s, many Native American tribes lived in this area. These included the Yuki, Pomo, Cahto, and Wintun tribes. Sadly, they faced many challenges. Their lands were taken, and many were forced into slavery. Attacks on their villages led to the Mendocino War in 1859, where many Native Americans lost their lives.
The Round Valley Indian Reservation was created in 1870. However, unfair treatment continued for many years. Other tribes from the Sierra Nevada mountains were also moved to this reservation. This forced march was called the "California Trail Of Tears." Many tribes who were not friendly with each other were forced to live together, which caused problems that still exist today.
Boundary Dispute with Trinity County
For a long time, there was a disagreement about the border between Mendocino and Trinity Counties. The state legislature first said the border was the 40th parallel north. A surveyor named W.H. Fauntleroy mapped this line in 1872.
Later, in 1891, a new survey found the line was actually 2 miles north of Fauntleroy's line. Both counties then claimed this 2-mile strip of land. They both tried to collect taxes from people living there. In 1907, Trinity County sued Mendocino County to solve the problem. The court decided that Fauntleroy's original survey, even if it wasn't perfectly accurate, was the official boundary. This decision was later confirmed by state law.
