Monowi is a village located in Boyd County, Nebraska. During the 2000 census, the village had a total population of 2; only one married couple, Rudy and Elsie Eiler, lived there. Mr. Eiler died in 2001, leaving his wife, Elsie Eiler as the only remaining resident. According to the United States Census Bureau, only 4 places in the United States had a population of one person in 2000: Ervings, New Hampshire, New Amsterdam, Indiana, Hibberts, Maine, and Lost Springs, Wyoming.

Monowi's peak years were in the 1930s, when it had a population of 130. Due to growing cities that offered more lucrative jobs, Monowi, like many other small towns in the Great Plains, lost its younger residents to the big cities.

Although almost nearly abandoned, the town does have the 5000-volume Rudy's Library, founded in memory of Mr. Eiler and maintained by Mrs. Eiler. In addition, Mrs. Eiler runs a tavern in Monowi and draws regular customers from as far away as 80 miles.
