What drivers in Mississippi are paying this week
Mississippi does not have a published weekly statewide average, so the reference number above is the Gulf Coast (PADD 3) average of $3.702. That regional benchmark fell $0.080 week over week and is $0.567 below the national average of $4.269. Stations in Mississippi typically trade within roughly 20 to 40 cents of the regional figure, depending on distance from the nearest terminal and local taxes.
Mississippi is almost always the cheapest state in the country or close to it. The state fuel tax is the lowest in the nation, and Gulf Coast refineries are next door.
Why Mississippi gas prices land where they do
- Lowest state motor fuel tax in the United States.
- Direct pipeline and truck access to Gulf Coast refining.
- Low retail operating costs in most counties.
These are structural factors, not daily noise. They explain why Mississippi tends to sit in the same part of the national price range week after week, even when the national average moves. For the general mechanics behind these forces, see our guide on how gas prices are set.
How Mississippi compares
Mississippi has no bordering state with a published weekly average, so the most useful comparison is the national average of $4.269 and the Gulf Coast (PADD 3) benchmark of $3.702. The state currently sits $0.567 lower than the national figure.
Ways to spend less on gas in Mississippi
- Membership warehouses such as Costco, Sam’s Club, and BJ’s usually price 10 to 30 cents below nearby branded stations.
- Stations a few miles off the interstate are often cheaper than the first exit, because they pay less for land and rely on local traffic.
- Apps that show station-level prices are worth using for the last mile — our numbers give you the regional baseline, they give you the address.
- Keeping tires at the recommended pressure and removing roof racks can recover 3 to 6 percent of fuel economy, which is worth 10 to 20 cents a gallon at current prices.

How we source Mississippi prices
Every figure on this page comes from the U.S. Energy Information Administration's weekly retail gasoline survey, which reports average retail prices in dollars per gallon including taxes. We rebuild the page every week after the survey is released, so the date on the price panel always matches the data behind it. We do not estimate missing state numbers; where the EIA does not publish a statewide series, we label the regional benchmark instead. Full details are in our methodology and data sources pages.
The bottom line for Mississippi drivers
At the regional benchmark of $3.702 per gallon, a 12-gallon fill-up in Mississippi costs about $44.42. Over a 15,000-mile year at 28 MPG, that implies roughly $1983 in fuel, before any local station discounts.
Mississippi gas price FAQ
What is the average gas price in Mississippi right now?
The U.S. Energy Information Administration does not publish a weekly statewide retail average for Mississippi. The closest official benchmark is the Gulf Coast (PADD 3) average, which was $3.702 per gallon for the week ending Oct 26, 2026. Local station prices in Mississippi typically fall within roughly 20 to 40 cents of that regional figure.
Is gas cheaper in Mississippi than the national average?
Mississippi is compared against the Gulf Coast (PADD 3) benchmark rather than a statewide number. The region averaged $3.702 versus the national average of $4.269, so Mississippi stations are best described as tracking below the national figure.
Why are gas prices low in Mississippi?
Lowest state motor fuel tax in the United States. Direct pipeline and truck access to Gulf Coast refining. Low retail operating costs in most counties. These factors matter more than the national average in determining what local stations charge, because fuel markets are regional, not national.
Where can I find the cheapest gas in Mississippi?
Station-level pricing is not part of the EIA dataset, so we do not publish a cheapest-station list. In practice, the lowest prices in Mississippi are usually at membership warehouses, at high-volume stations on secondary roads rather than interstate exits, and at stations in lower-cost suburban counties. Use a station-level price app for the final address and our Mississippi benchmark to judge whether the price you see is reasonable.
Will gas prices go down in Mississippi?
Nobody can forecast a specific week with confidence. What can be said is mechanical: Mississippi prices follow crude oil costs, regional refining capacity, seasonal fuel specifications, and local taxes. When crude falls and refineries run normally, prices usually follow within two to four weeks. When a refinery goes down or a hurricane threatens the Gulf Coast, the move can reverse within days.
