Pacific Avenue is two formerly connected north-south roads in Sutter County.

The larger portion of Pacific Avenue runs between Rio Oso Road in Rio Oso (east of the Union Pacific Railroad tracks and Highway 70) and Howsley Road in Pleasant Grove. This portion also passes through Trowbridge and Catlett. Significant places on this portion of Pacific Avenue include Browns Elementary School (which also houses the Sutter County Library Browns Branch) and both the Fairview Cemetery and Fairview Community Christian Church. East Nicolaus High School sits at the intersection of Pacific Avenue and Nicolaus Avenue in Trowbridge.

The separate, shorter portion of Pacific Avenue runs between Sankey Road in Sankey and Riego Road in Counsman.

There is also an unrelated road in Olivehurst that is called Pacific Avenue. It runs north-south between 7th Avenue and 11th Avenue.
