Montgomery County is a county located in the southwestern part of Iowa, a state in the United States. In 2020, about 10,330 people lived here. The population has changed over time, with fewer people living here now compared to the early 1900s. This is partly because more people moved to cities and there are fewer family farms.

The main town and county seat is Red Oak. The county was started in 1851 by people who moved from eastern areas. It was named to honor Richard Montgomery. He was a general during the American Revolutionary War who died in 1775.

Montgomery County has mostly been a rural area, meaning it has a lot of farms. The land was first measured and mapped in 1852. It is also known as the place where the Villisca axe murders happened in 1912. This event is still an unsolved mystery. Clyde Cessna, who started the famous Cessna Aircraft Company, was born in this county.
