Gas Prices in Boston
Boston has above-average gas prices driven by New England's supply chain isolation and high operating costs, though Massachusetts's moderate 24¢ tax prevents Boston from reaching Connecticut or Rhode Island-level prices. Cumberland Farms is the most competitively priced chain in the metro.
Prices at individual stations can vary by 5–15 cents within the same city depending on brand, location, and local competition. Use apps like GasBuddy to find the cheapest station near you in Boston.
