Waldo Junction (formerly Waldo and Cabbage Patch) is an unincorporated community in Yuba County, California. It is located on Dry Creek 9.5miles northeast of Wheatland, at an elevation of 256 feet (78 m).
A post office operated here from 1898 to 1915. Originally called Cabbage Patch in 1852, the name changed to Waldo upon the opening of the post office. The name honors William Waldo, an early settler. Other sources, however, state the name honors Waldo Johnson, a prominent attorney of Marysville.[1]
