Berea was an unincorporated community in Eureka Township, Adair County, Iowa, United States.

[3] The community was founded by Ned Brown and Alexander Broadfoot, who were early settlers, and its peak population was around 100 residents.

[5] In 1905, the community was reported to have a population of 40, with a general store, a pharmacist, a creamery, a blacksmith and a wagonmaker.

[4] The Rock Island Railroad passed through nearby Anita and Adair, and it was for this reason that Berea began to decline.

In 1936, the Berea School closed due to lack of pupils, and by the 1940s, the community was called a "ghost village".
