Cavalier County is a county in the U.S. state of North Dakota. It is south of the Canada–US border with Manitoba. As of the 2020 census, the population was 3,704. Its county seat is Langdon. The city of Cavalier is in nearby Pembina County.


Cavalier County was created from the western part of Pembina County, North Dakota in 1873 and named by the Territorial Legislature for Charles Turner Cavileer (1818–1902), a well known fur trader, customs agent and postmaster. There is no explanation for the difference in the spelling of "Cavalier," though one placename historian suspects it was an attempt to Gallicize, or make the name appear French.

After petitioning the Territorial Governor for permission to organize the county, Patrick McHugh, W. Hudson Matthews, and L.C. Noracong met for the purpose on July 8, 1884. On July 26 the new county officials met for the second time and chose Noracong as Chairman of the Board with William H. Doyle and Matthews as Commissioners. The first Register of Deeds and County Clerk was McHugh. W.J. Mooney became the first Judge of Probate, Charles B. Nelson was the first Cavalier County Supt. of Schools, and Clarence Hawkes the first Sheriff. Cavalier took its current form in 1887 after the Territorial Legislature authorized an increase in size by taking a portion from Pembina County. The expansion added 15 new townships to the county.

The site of the new county seat was chosen at this meeting and named Langdon after Robert Bruce Langdon of Minnesota and official with the Great Northern Railroad. Langdon never visited the town, but reportedly donated a bell for the local school.

The first court house was built in the fall of 1884 at a cost of $360.00. It was used briefly and then abandoned for warmer and more centrally located quarters in a downtown bank. A large brick court house was built in 1895 on the present site at a contract cost of $9,099.00. This building served county officials until the current court house was constructed in 1957-58.

Cavalier County Historical Society

Established after 1969 - The Holy Trinity Church at Dresden, ND became the cornerstone of the County museum. It now houses local historic artifacts and landmarks.

The Holy Trinity Church at Dresden replaced two previous wooden structures that both burned. The present structure was erected in 1936, built out of fieldstone collected by the local parishioners. An architect from Minneapolis, Fabian Redmond, designed the building. A stonemason from Rugby ND, Edroy Patterson, directed volunteer workers.

Assisting in the building of the church were Andrew Bachman-head carpenter, Alphonse Hiltner, Stanley Koehmstedt and William Geisen.


According to the U.S. Census Bureau, the county has a total area of 1,510 square miles (3,900 km2), of which 1,489 square miles (3,860 km2) is land and 21 square miles (54 km2) (1.4%) is water.
