Valencia Park is an urban community in the southeastern section of San Diego, California, United States. It is bordered by Emerald Hills and Market Street on the north, Lincoln Park and Euclid Avenue to the West, Encanto to the east, and Alta Vista and National City, California, to the south. Major thoroughfares include Imperial Avenue, Churchward Street, and Valencia Parkway.

The resident and San Diego real estate entrepreneur Astor Basmajian donated part of the property to Valencia Park Elementary (playground area). An earlier resident of this community, Astor bought several pieces of property within Valencia Park and in San Diego County. From buying and selling homes that were already there and building a subdivision of new homes within the neighborhood later named Astor Heights, he helped contribute to the earlier history of the Valencia Park community. Astor Basmajian, an immigrant from Armenia, escaped the genocide early and became a millionaire twice in his lifetime. A jeweler by trade, he and his brother opened a jewelry shop in New York shortly before World War I. Both brothers served in the war. After returning from the war, Astor continued his business and later moved to Ohio and California, where he remained the rest of his life, living out the "American Dream."

With the great influx of Filipino immigrants joining the United States Navy, especially from the Vietnam War era on to the 1990s, many Filipinos inhabited the Southeast San Diego neighborhoods of Alta Vista, Bay Terraces, Paradise Hills, Shelltown, Skyline Hills, and Valencia Park, both for the relatively affordable housing prices and its proximity to Naval Base San Diego.
