Glen Allen is a village in central Bollinger County in Southeast Missouri, United States, located near the intersection of State Highway 34 and Route ZZ just west of Marble Hill. The population was 57 at the 2020 census.[3]
It is part of the Cape Girardeau - Jackson, MO-IL Metropolitan Statistical Area.
Glen Allen was settled circa 1870 and incorporated as a town in 1906. It was situated along the St. Louis, Iron Mountain and Southern Railway.[4]
In the early morning hours of April 5, 2023, an EF-2 tornado ripped through Glen Allen causing widespread destruction and a number of injuries, including five fatalities.[5]
