Santa Rosa gas prices
$6.11 / gal Regular average · 47 locations
How we compare prices
Regular gasoline only. We compare the city average today with its average yesterday and on the same date last month. Each average uses the available stations at that time, with prices no more than 36 hours old. The mix of stations and payment conditions can change, so this is an indicative city trend.
Yesterday: Oct 21, 2026: $6.152/gal, 46 locations. Last month: Sep 22, 2026: 2 locations. Cutoffs use the same local time in California; a shorter month uses its last day. Monthly comparisons need at least 3 stations on each date; daily comparisons need 12. Past averages are reconstructed from recorded observations.

A North Bay base for a wider outing
Santa Rosa is Sonoma County's county seat and a major city in the North Bay's wine-country region. The city can be a destination in its own right or a base for a longer rural outing. Those uses call for different fuel plans: a local average does not describe prices at every stop beyond the city.
Include the next rural destination
If you are continuing beyond Santa Rosa, enter that destination before choosing where to refuel. For a downtown stay, compare along your arrival route instead. Confirm station hours independently when planning a late return; missing hours in our catalog mean unknown information, not a closed station.

Catalog locations and recent price observations are different measures. Records here use the Santa Rosa city address label; this is not a census of every station within the municipal boundary. Separately named neighborhoods may appear on their own pages.

- 8 with food information
- 9 with recorded opening hours
Missing details mean unknown information, not that a service is absent. Recorded amenities and hours can change. Known restricted sites are excluded from this catalog count; access at other sites may still be unconfirmed. Check the individual location before traveling.

Why your route still matters
A city average cannot identify the stop worth making. WorthStop ranks eligible stops for the route using the selected fuel grade, gallons, vehicle MPG and extra driving required.
