Rancho Bernardo is a sprawling community with shopping centers, golf courses, and office parks typical of San Diego development located about 20 miles north-northeast of downtown San Diego, immediately east of 4S Ranch, north of Carmel Mountain Ranch, northwest of the city of Poway, and south of the city of Escondido.

The Carmel Mountain Ranch/Rancho Bernardo submarket is the fifth largest office space submarket in San Diego County, with over 6 million square feet of office space. 

There is an annual carnival-type street fair, RB Alive!, during the summer. Rancho Bernardo is also home to the oldest-operating winery in the region, the Bernardo Winery, established in 1889 and family-owned and operated since 1927.

Rancho Bernardo is home to the Corporate Headquarters of Sony Electronics, Inc. and a major office of Sony Interactive Entertainment, LLC. Other companies with a presence in the area include Broadcom, Hewlett-Packard, Microsoft, Teradata, LSI Corporation, BAE Systems, Northrop Grumman, and Amazon. Located in a 685 acres business park, there are approximately 50,000 workers employed by these companies.

The area is part of the Poway Unified School District.
