Downtown San Diego (also referred to as Centre City) is the city center of San Diego, California, U.S. and the central business district of San Diego County. In 2004, Centre City San Diego had a population of 28,586.

Centre City San Diego is delimited by San Diego Bay to the west and southwest, Bankers Hill, Middletown, and Balboa Park to the north, Sherman Heights and Golden Hill to the east, and Barrio Logan and Logan Heights to the southeast. San Diego International Airport is just northwest of downtown.

In the past decade, downtown San Diego has benefitted from revitalization and redevelopment and has become a vibrant live, work, play community. CCDC has been actively redeveloping downtown, and it is now a highly desirable address.
