Eagle Grove was platted in 1881. It was named from the eagle nests seen by early settlers in a nearby Oak tree grove perched above the bank of the Boone River. In 1851 Mr. N. B. Paine moved to Wright County, purchased property and constructed a log cabin that stood directly west of the grove. The nest was over six feet in diameter.
