Average gasoline prices in Chattanooga have risen 8.5 cents per gallon in the last week, averaging $3.38/g on June 22, 2026, according to GasBuddy’s survey of 170 stations in Chattanooga.

GasBuddy says prices in Chattanooga are 72.5 cents per gallon lower than a month ago and stand 61.8 cents per gallon higher than a year ago.

The national average price of diesel has decreased 19.2 cents compared to a week ago and stands at $4.990 per gallon.

According to GasBuddy price reports, the cheapest station in Chattanooga was priced at $2.95/g yesterday while the most expensive was $3.79/g, a difference of 84.0 cents per gallon.

“Average gasoline prices declined in nearly every state over the last week, while all 50 states saw average diesel prices move lower,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “However, the outlook is far from settled. New uncertainty has emerged after Iran suggested the Strait of Hormuz was closed, along with fresh warnings that the U.S. could again strike Iran, developments that could push oil prices higher in the days ahead. Despite this, gasoline prices aren’t yet at significant risk of a spike, as some vessels have continued to move through the Strait. Still, should the situation worsen or escalate further, motorists could see that risk change quickly.”

The national average price of gasoline has fallen 14.1 cents per gallon in the last week, averaging $3.85/g on June 22, 2026.
