McKinleyville is a community made up of a combination of smaller settlements. Joe Dow settled in the general area in the 1860s and that area was known as Dow's Prairie. Slightly south was a small community called Minor (also known as Minorville). Minor was first settled in the late-19th century. Just south of Minor was Calville. Calville was settled by the employees of the California Barrel Company. After President William McKinley was assassinated in 1901 the community of Minor changed its name in his honor. All three areas are collectively considered to be what is now known as McKinleyville. Dow's Prairie continues to be known by the original place name and, although it is considered part of McKinleyville, local residents further refine location by this neighborhood name. , 
The first post office at McKinleyville opened in 1903, closed in 1921, and was re-opened in 1955.
