About gas prices in Mississippi
Mississippi has one of the lowest state gas taxes in the country at roughly 18 cents per gallon and draws fuel directly from Gulf Coast refineries in Louisiana plus the Chevron Pascagoula refinery on the Mississippi coast. Jackson, Gulfport, and Hattiesburg all post pump prices among the lowest in the nation. Murphy USA at Walmart locations leads on value across smaller cities, with Sam's Club and Costco dominant in Jackson, Gulfport, and Hattiesburg metros. Buc-ee's has expanded into Mississippi and pulls aggressive low pricing at its locations. Coastal Mississippi occasionally sees hurricane-related price spikes when Gulf refining capacity is disrupted, but recovery is typically faster than Texas or Louisiana.
