Lodi ( LOH-dye) is a city located in San Joaquin County, California, United States, in the center portion of California's Central Valley. The population was 66,348 at the 2020 census. Lodi is best known for wine grape production, although its vintages have historically been less prestigious than those of Sonoma and Napa counties. However, in recent years, the Lodi Appellation has become increasingly respected for its Zinfandel and other eclectic wine varietals, along with its focus on sustainability under the Lodi Rules program. National recognition came from the Creedence Clearwater Revival song "Lodi" and continued with the "2015 Wine Region of the Year" award given to Lodi by Wine Enthusiast magazine.
