Coal Valley is an extinct town in Boone County, in the U.S. state of Iowa. The GNIS classifies it as a populated place.
Coal Valley was platted in 1867 as a coal mining community.[1] Once the coal deposits were exhausted, Coal Valley's business activity shifted elsewhere and its population dwindled. The former town site now is farmland.[2]
