Carlotta is an unincorporated community in Humboldt County, California. It is located  southeast of Fortuna, at an elevation of , about  east of US Route 101 on California State Route 36.

History
Carlotta is named after Carlotta Vance, daughter of John M. Vance, who laid out the town as a summer resort. The first post office at Carlotta opened in 1903.

At that time, it had several cottages, a hotel, store, blacksmith and saloon. Around 1915, a large farm at Carlotta was converted into a branch of Cottage Garden Nurseries, a company headquartered in New York; an orchard and thousands of ornamental plants were installed. Prohibition did in the saloon for a decade, and the depression of the 1930s reduced resort business, but the logging boom following World War II resulted in the construction of two large mills and housing for workers surrounding the town.

The hotel was essentially unchanged in 1975 which the National Register application form was filed.  It was  with a kitchen annex which burned down in 1974.   The hotel was three stories high with dormers on a hip roof, wood shingle on the upper two stories but board and batten below.   A veranda with gingerbread features ran the full length of the face and around the south side.   Both ends had brick chimneys on the outside.   The building was one of several resorts on the Overland Stage Route, today's Route 36. The hotel was known for popular Sunday dinners, Fourth of July celebrations, races and games; the clientele arrived and departed by train from Eureka.

The Vance family sold the town of Carlotta to local investors, including two of the local shopkeepers, in December 1921.  The hotel remained under the same ownership from 1921 to 1977 when the heirs sold it, although it was also closed for several years in the 1920s to 1930s until being run by Joe Matteucci starting around 1936.   The Matteucci family operated the hotel and restaurant for about 30 years. The Carlotta Hotel was nominated to the National Register of Historic Places for significant architecture, little change since construction and a representative of roadside hotels.

The town and hotel were sold to Angelo Batini in 1977 who reopened the Carlotta Hotel in 1984. The hotel and restaurant operated until an electrical fire in the mid-1990s destroyed the building.

In 2006, the two abandoned mills were still standing, but most of Carlotta's residents commute to Fortuna or Eureka for work.
