The Farmers Mutual Reinsurance Company Building is a historic structure located in Grinnell, Iowa, United States. "The Iowa Farmers Mutual Reinsurance Association was the first statewide organization of its kind in the United States." When it moved to Grinnell from Jefferson, Iowa in 1934 its name was changed to Farmers Mutual Reinsurance Company. It was still a relatively small operation at the time that required only simple rented upstairs quarters. The present building was first occupied in 1951, but only the first two floors were built. The top two floors were completed in 1957, and gave the building its present form. The company rented out the first floor to other commercial businesses. Farmers Mutual Reinsurance Company moved out of building in 1962 to a larger complex south of Grinn
