Balboa County, California

Veronica Mars is an American television series created by Rob Thomas. The series premiered on September 22, 2004, during UPN's last two years, and ended on May 22, 2007, after a season on UPN's successor, The CW Television Network. Set in the fictional town of Neptune, the series starred Kristen Bell as the title character, a student who progressed from high school to college during the series while moonlighting as a private investigator under the wing of her detective father.

Neptune, California is the series' fictional setting, a US unincorporated town in Balboa County. The town is described as without a middle class, and the upper class is known as "09ers", wealthy citizens from the fictional 90909 ZIP code. The nearby towns, at some distance from the beaches, do not have the same extremes between rich and poor.

Neptune is a coastal community located between San Diego and Los Angeles on the route of California's Pacific Coast Highway. Many locations in California are named after Vasco Núñez de Balboa, including the Balboa Peninsula section of Newport Beach in Orange County and San Diego's Balboa Park. In reality, State Route 1 does not run south of Orange County. In season 1, it is implied that Neptune is about 85 miles (or a 90-minute drive) from San Diego. Series creator Rob Thomas stated in an interview that Neptune is located near San Juan Capistrano in Orange County.
