Maryland gas prices
Maryland gas prices tend to hover right around the national average or slightly above. The state is in the mid-Atlantic region with decent pipeline access but no refineries of its own. Fuel comes via the Colonial Pipeline and from the Philadelphia refinery complex.
The DC metro area drives most of Maryland's demand. Prices in the Baltimore-Washington corridor tend to be higher than the Eastern Shore or western Maryland. State gas taxes are moderate. Maryland temporarily suspended part of its gas tax in 2022 during the price spike, which brought brief relief, but the full tax has since been restored.
Price history
Why do gas prices vary across Maryland?
The Baltimore-Washington corridor has higher demand, more traffic, and higher operating costs for stations. The Eastern Shore and western Maryland are more rural with slightly lower prices but fewer stations to choose from.
Does Maryland have any refineries?
No. Maryland imports all its fuel, primarily via the Colonial Pipeline from the Gulf Coast and from refineries in the Philadelphia area. This puts the state at the end of a supply chain, which adds a few cents per gallon.
How do Maryland gas prices compare to Virginia?
Maryland is usually a few cents more expensive than Virginia. Virginia has slightly lower gas taxes and better direct access to the Colonial Pipeline terminals. Many DC-area commuters who live near the border fill up on the Virginia side.
