Langdon is a city in Cavalier County, North Dakota, United States. It is the county seat of Cavalier County.  The population was 1,878 at the 2010 census.  Langdon was designated as the county seat in 1884 and was incorporated in 1885.
On Memorial Day (then called Decoration Day) 1909, a tornado struck on the prairie a mile to a mile and a half southeast of Langdon, then moved seven miles in a northwest direction.  The tornado, locally dubbed The Vulcan, killed five people and injured 29.  Notably, Mrs. M.L. Sullivan ran for safety but the tornado hit as she arrived at her cellar door.  When the winds subsided, she was standing in the cellar with its broken doorknob in her hand.  Katie Diamond was lifted above treetops and telephone poles, and then dropped in a yard, virtually unscathed.  The tornado destroyed many barns, two elevators, the Great Northern water tank and several feet of railroad track. 
Langdon is located at (48.761696, -98.371780).

Langdon's high school underwent a name change because of surrounding schools closing. The school was renamed "Langdon Area High School" (instead of "Langdon High School") in the fall of 2001. The mascot of Langdon Area High School is the Cardinal.
Students from Langdon Area Schools perform better than state averages in several areas. Graduation rates, for example, typically exceed state averages by several points. Since 2005, in all areas where comparable statistics were available, Langdon outperformed state averages from 4.5% to 15.4%. 
Langdon's students also tend to outperform their District's Adequate Yearly Progress goals in both the proficiency and participation categories. In some cases, these differences are quite significant. For example, the District's 2007-2008 proficiency goal in mathematics was 65.5%, whereas the district's actual proficiency was measured at 97.7%, a difference of 32.2%.  A similarly large difference can be seen in reading proficiency scores. Despite this high achievement, however, the District is not considered by the state to have achieved Annual Yearly Progress in the 2007-2008 school year. However, this may be a statistical anomaly given the District's consistently high performance in previous years. For example, in the 2006-2007 school year, reading participation was 100% and mathematics participation was 99.5%. Even though the 2007-2008 rates in these areas were very high (97.7% in both cases) such a score still represents a decline from previous years. Similar patterns of small declines from already high figures can be seen in the areas of graduation rates (0.4% decline, from 95% to 94.6%) and attendance (0.1% decline, from 97.3% to 97.2%). These small changes may keep the District from being listed as having made adequate yearly progress, despite their high overall proficiency. Additionally, in some areas the 2007-2008 figures represent significant improvement over those from the 2006-2007 school year, where Landgon underperformed state averages in the key areas of reading (-10.2%) and mathematics (-7.4%) proficiency. This indicates a positive trend for the District, although one which will need to reevaluated when the 2008-2009 data become available to determine whether it is part of a larger pattern or not.
In addition to student academic performance, average daily attendance at Langdon Area Schools is slightly higher than the state average (97.2% versus 96.7%), a general pattern which has held true since at least 2005. 
This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Langdon has a humid continental climate, abbreviated "Dfb" on climate maps. 
The town was devastated by a tornado in May 1909.
