Calneva is an unincorporated community in Lassen County, California. It is located 10 miles (16 km) north-northeast of Doyle, at an elevation of 4009 feet (1222 m). Calneva is on the Nevada state line—its name is a portmanteau of California and Nevada. During the 1916 New York City polio epidemic a quarantine officer was stationed there to medically examine passengers from New York, New Jersey and Chicago in an attempt to prevent the disease spreading to California. A post office operated at Calneva from 1911 to 1919, and from 1920 to 1933.
