which state has the cheapest gas

Oklahoma currently has the cheapest average gas prices in the United States, with regular unleaded around the mid‑$2.30s per gallon as of mid‑December 2025.

Quick scoop

• Cheapest state right now: Oklahoma, with an average price reported at about $2.37 per gallon in early December 2025.

• Other low‑cost states include Colorado, Texas, Arkansas, and Iowa, all in the mid‑ to high‑$2.00 range on average.

• The national average is closer to the high $2.00s, so Oklahoma is notably below the U.S. norm.

Why Oklahoma is so cheap

• Lower state fuel taxes help keep pump prices down compared with high‑tax states like California and Hawaii.

• Proximity to refining and pipeline infrastructure in the central U.S. also tends to reduce transport and distribution costs.

How fast this can change

• State rankings can shift week to week with changes in crude prices, refinery outages, or weather events.

• For the most up‑to‑date number before you fill up, check a real‑time gas‑price tracker (like AAA’s state averages or an app such as GasBuddy) on the day you plan to buy.

Recent trend context

• As 2025 winds down, average U.S. gas prices have generally eased compared with a year ago, with more states dipping below $3 per gallon.

• The spread between the cheapest states (like Oklahoma) and the most expensive (like California and Hawaii) is now more than $2 per gallon in some snapshots.

TL;DR: Oklahoma is the state with the cheapest average gas right now, sitting well below the national average, with several other central and southern states not far behind.
