Gas Prices in Overland Park, KS Today

Overland Park drivers are paying around $3.15 per gallon for regular unleaded in late March 2026, well below the national average of $3.91 and consistently cheaper than their counterparts just across State Line Road in Kansas City, Missouri. This isn't coincidental. The state line running through the Kansas City metro creates a measurable, consistent price differential that Overland Park residents quietly benefit from every time they fill up.

The State Line Price Gap

Missouri and Kansas have different gas tax structures, and the difference shows up at the pump in the KC metro. Missouri's gas tax is 19.9 cents per gallon, one of the lowest in the country. Kansas's gas tax is 24 cents per gallon. On paper, that would seem to make Missouri cheaper, but the full picture includes each state's combined regulatory burden, environmental compliance costs, and the blend specifications required in the Kansas City metro area (a federal nonattainment zone for ozone that requires reformulated fuel).

In practice, Overland Park, Johnson County, KS, runs 5–15 cents cheaper per gallon than comparable neighborhoods on the Missouri side of the line. Johnson County is one of the wealthiest counties in Kansas, and while that usually correlates with higher prices, the intense station density along Metcalf Avenue, 135th Street, and College Boulevard creates real competition that keeps margins tight. High-income consumers are still price-conscious when it comes to frequent, predictable purchases like fuel.

The Suburban Competition Advantage

Overland Park has an exceptionally high ratio of warehouse club and grocery-anchor fuel stations relative to its population. Costco (off 135th Street), Sam's Club, Walmart Neighborhood Market fuel centers, and Hy-Vee Gas all compete in the same south Johnson County market. Each of these operators prioritizes fuel volume as a membership or loyalty driver and routinely prices well below the street average.

The result is a market where checking one or two of these options before a fill-up can save $0.25–0.40 per gallon over a nearby branded station. In Overland Park, unlike in less competitive suburban markets, the cheap option is rarely out of your way.

Where to Find the Cheapest Gas in Overland Park

The southern and central corridors of Overland Park have the most competitive pricing. The northern edge (closer to Mission and Shawnee Mission Parkway) sees slightly higher prices due to older, smaller stations with less competitive scale.
