Gas Prices in Clarksville, TN Today

Clarksville drivers are paying around $3.20 per gallon for regular unleaded in late March 2026, below both the Tennessee state average and the national average of $3.91. Tennessee is one of the cheapest states in the country for fuel, and Clarksville has the additional advantage of being the commercial hub for Fort Campbell, one of the largest military installations in the United States. That combination of state-level tax advantages and military-driven price competition keeps fuel costs here meaningfully lower than in comparably sized cities.

Fort Campbell and the Military Competition Effect

Fort Campbell is not just a Clarksville neighbor, it is a defining force in the local economy and its fuel market. The installation straddles the Tennessee-Kentucky state line (the main gate is technically in Kentucky, but the city of Clarksville, TN is the primary off-post hub) and houses the 101st Airborne Division along with tens of thousands of soldiers, family members, and civilian employees.

Fort Campbell's on-post fuel station through AAFES (Army & Air Force Exchange Service) prices fuel without state or federal fuel taxes, typically running 30–50 cents per gallon below the local commercial average. Service members and their families with access to the post use this regularly and effectively. The presence of that large, price-aware military consumer base puts consistent downward pressure on commercial stations in Clarksville: those stations know they're competing with a tax-free on-post option, and it shows in how aggressively they price.

The station density on Wilma Rudolph Boulevard, Fort Campbell Boulevard, and US-41A (the primary corridors between the post gates and the city) is high, and the competition is real. Commercial stations on these corridors run some of the tightest margins in Montgomery County.

Tennessee's Gas Tax Structure

Tennessee's state gas tax is 26 cents per gallon, one of the lower rates in the Southeast. Tennessee also has no state income tax on wages (it taxes investment income but not earned wages), which contributes to a generally lower overall state tax burden. The combination keeps retail fuel margins lean statewide, and Clarksville benefits as much as any Tennessee city.

The state's location, between the Gulf Coast pipeline corridor and the Midwest refinery distribution network, gives Tennessee good supply access without excessive haul costs. Nashville-area wholesale terminals serve Clarksville with relatively short delivery runs.

The Kentucky Border Dynamic

Because Fort Campbell straddles the TN/KY line, some Clarksville-area residents are close enough to Hopkinsville, KY to consider crossing for fuel. Kentucky's gas tax is 26 cents per gallon as well, roughly equivalent to Tennessee's, so there's no structural tax-arbitrage benefit to crossing the state line here (unlike the Indiana-Illinois or New Hampshire-Massachusetts situations in other markets). The relevant border fact is simpler: off-post stations on both sides of the line compete for the same Fort Campbell consumer base.
