Loup City is a city in Sherman County, Nebraska, United States. The population was 996 at the 2000 census. It is the county seat of Sherman County. Loup City sits close to the Middle Loup River, and about 10 miles from Sherman Reservoir (a reservoir created from diverting water from the Middle Loup River). During the Great Depression, Loup City was the site of a clash between radical leftists, influenced by Mother Bloor, who clashed with area residents in June 1934 following efforts by Communists to organize the workers of a poultry processing plant. For many years Loup City has proclaimed itself as the "Polish capital of Nebraska," due to a significant Polish population. "Polish Days" is an annual community event. The town's Catholic church, Saint Josaphat's, features stained glass windows commemorating area families, most with Polish names. The windows were salvaged from the previous St. Josaphat's and date from the early 1900s.
