Horace is a city in Cass County, North Dakota, United States.

Horace was founded in 1882 at a time of widespread European-American settlement in the territory.

[7] Greeley encouraged western settlement with the motto "Go West, young man".

To reduce damage from seasonal flooding, which sometimes was severe, the state and federal government collaborated on the Sheyenne Diversion Project, constructing a canal and associated support in 1990–1992 to move Sheyenne flood waters to the west and south of Horace, and north past the western side of West Fargo.

This has proved its worth, protecting the Sheyenne cities from damage that resulted from the large 1997 Red River flood, which destroyed areas of Grand Forks and East Grand Forks to the north.
