The Arkansas General Assembly defined the state's 64th county on March 22, 1871, and named it Sarber County for John N. Sarber, the Republican state senator from Yell County who had introduced the resolution. The senator was viewed as a carpetbagger, and after the Reconstruction Era state government was replaced the county was renamed for James Logan, an early settler in the area, on December 14, 1875. 
According to the U.S. Census Bureau, the county has a total area of 732 square miles (1,900 km2), of which 708 square miles (1,830 km2) is land and 23 square miles (60 km2) (3.2%) is water.  The highest natural point in Arkansas, Magazine Mountain at 2,753 feet (839 m), is located in Logan County.

Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States Census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Logan County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.
