Fallon is an unincorporated community in Morton County, North Dakota, United States.

[2] The settlement started to develop in the late 1890s, and a post office was opened April 2, 1900 with James A. Fallon, a native of Ireland, as Postmaster, who is also most likely the town's namesake.

The peak population was only about 10 people, due to the towns inland location away from an operational railroad or highway, thus very little development ever occurred.

Today, there are currently two buildings left at the site, a community center or possibly town/dance hall, and a house, formerly the church Parish, which appears to have been last occupied in 2008.

In summer 2017, a man briefly moved to the townsite in two RV's to the north of the house, but his presence didn't last long.
