As of May 30, 2026, the average regular unleaded gas price in Massachusetts is $4.414 per gallon, up 46.6% from $3.010 a year ago
The current average gas price in Massachusetts stands at $4.414 per gallon for regular unleaded fuel, according to AAA data as of May 30, 2026. This represents a sharp year-over-year increase from $3.010 per gallon in May 2025, reflecting regional supply constraints and elevated winter demand for LNG-powered heating that tightens natural gas feedstock availability for gasoline refining.
Massachusetts Gas Price Breakdown by Fuel Grade (May 30, 2026)
| Fuel Grade | Current Average (MA) | Year Ago Average | Year-Over-Year Change |
|---|---|---|---|
| Regular Unleaded | $4.414 | $3.010 | +46.6% |
| Mid-Grade | $4.992 | $3.607 | +38.4% |
| Premium | $5.381 | $3.990 | +34.9% |
| Diesel | $5.689 | $3.772 | +50.8% |
Regional Price Variations Across Massachusetts Counties
Gas prices vary significantly across Massachusetts regions, with Boston metro prices reaching nearly $4.30 per gallon-the highest in the state-while Bristol County on the southeastern coast averages just $4.07 per gallon. The North Shore (Middlesex and Essex counties) starts at $4.17 per gallon, and the three counties south of Boston (Bristol, Plymouth, and Barnstable) range between $4.07 and $4.11.
- Bristol County: $4.07 (lowest in state)
- Plymouth County: ~$4.09
- Barnstable County: ~$4.11
- Middlesex & Essex (North Shore): $4.17+
- Suffolk County (Boston): ~$4.30 (highest)
How LNG Infrastructure Shapes New England Gas Prices
Liquefied natural gas (LNG) plays a critical role in New England energy security, meeting over 25% of regional daily natural gas demand since November 2010. Four LNG regasification facilities serve the region: Canaport (New Brunswick, Canada), Everett (Boston), Neptune, and Northeast Gateway. Most LNG deliveries come from Canaport and Everett terminals, with Canaport's U.S. shipments recorded as pipeline imports from Canada.
The Northeast Energy Center (NEC) in Charlton, Massachusetts, began commercial operations on April 1, 2024, marking a shift toward energy self-sufficiency for New England. This domestically sourced natural gas plant insulates the region from global energy commodity volatility and overseas logistics, providing LNG storage and liquefaction services to Boston, Rhode Island, and all of New England.
- LNG facilities provide critical peaking capacity during winter heating demand
- Pipeline constraints from North American gas-producing regions limit supply during high-demand periods
- Domestic LNG reduces reliance on foreign overseas imports that previously dominated New England
- NEC's liquefaction services enable regional storage for winter peak demand management

Massachusetts vs. National Gas Price Comparison
While Massachusetts gas prices have edged up recently, they remain below certain historical peaks but are now significantly higher than last year. The price differential dynamics reflect New England's unique supply constraints and LNG-dependent heating infrastructure that competes with refining feedstock during winter months.
Historical monthly data for Boston-Cambridge-Newton shows regular gasoline at $4.007 per gallon in April 2026, rising from $3.554 in March 2026 and $2.941 in February 2026. This sharp winter-to-spring price trajectory underscores how LNG heating demand compresses natural gas availability for gasoline production.
