Langdon is a city in Cavalier County, North Dakota, United States.

[7] The city was named for Robert Bruce Langdon, a politician and railroad official.

It was alleged that the Langdon precinct had cast 150 votes with a total of only 50 qualified voters.

[10] The Vulcan was part of an outbreak of tornadoes called the Decoration Day Massacre, the second deadliest tornado outbreak in North Dakota's recorded history, killing 12 people in Langdon and surrounding communities.

Sullivan ran for safety but the tornado hit as she arrived at her cellar door.

[10] Katie Diamond was lifted above treetops and telephone poles, and then dropped in a yard, virtually unscathed.

[10] The tornado destroyed many barns, two elevators, the Great Northern water tank and several feet of railroad track.

Graduation rates, for example, typically exceed state averages by several points.

[17] Langdon's students also tend to outperform their District's Adequate Yearly Progress goals in both the proficiency and participation categories.

However, this may be a statistical anomaly given the District's consistently high performance in previous years.

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.

These small changes may keep the District from being listed as having made adequate yearly progress, despite their high overall 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.
