Charles Xavier "C. X." Larrabee (November 19, 1843 – September 16, 1914) was a 19th-century businessman and a co-founder of the town of Fairhaven, Washington. Later in life, Larrabee and his wife Frances donated much land for civic purposes, including schools and parks, and were considered stewards of the city of Bellingham.
Larrabee was born in 1843 to William and Mary Ann Larrabee in Portville, New York, and was only six years old when the family moved to Omro, Wisconsin in 1849, where his father opened a general store. Once he was old enough, Larrabee traveled to Poughkeepsie, New York to take a course at a business college to add to his public education. Starting in 1869, Larrabee and his brother, Samuel E. Larabie (1845–1914), operated a bank in Deer Lodge, Montana.
In 1875, he went to Montana, and in 1887, his efforts as a prospector were rewarded by the discovery of the valuable Mountain View near Butte. After selling this property to the Boston & Montana Company, he moved to Portland, Oregon. In 1890, he arrived in Bellingham, Washington and associated himself with Nelson Bennett, the founder of Tacoma, Washington. Together they started the town of Fairhaven and formed the Fairhaven Land Company, which was financed by Larrabee, who was also president of the company in 1896. Larrabee later purchased the land company holdings of his partner and retained control of the corporation until his death, doing work in land development, including building the Fairhaven Hotel, described by one reporter of the Fairhaven Herald as "million-dollar edifice."
