The latest data from AAA shows a modest nationwide dip in gasoline prices, with the US national average at $4.048 per gallon as of April 19, 2026. While the overall trend points to slight relief for drivers, the divide between the most expensive West Coast and island markets and the more affordable Southern and Midwestern states remains pronounced.

States along the Pacific coast and in the Pacific islands continue to dominate the high-price list, while parts of the South and Great Plains are offering some of the lowest pump prices in the country.
