Vallco Shopping Mall (formerly called Cupertino Square and originally Vallco Fashion Park) is a mostly-demolished dead mall located in Cupertino, California, United States. Originally built as a two-story shopping mall in 1976 with a third-level movie theater added in 2007, it was anchored for most of its existence by Macy's, Sears, and J.C. Penney. As of August 2022^[update], the mall is owned by Sand Hill Property Co. and is almost entirely vacant, with Cupertino Ice Center (formerly the Ice Capades Chalet), Bowlmor Lanes, and Benihana as the only remaining tenants, all in the section to the east of Wolfe Road. The larger western portion of the main mall structure was demolished in August 2019, followed by the demolition of the pedestrian overpass in March 2020. Plans for the site include a mixed-use development featuring office space, housing, and retail.

A plan by Sand Hill to rebuild Vallco as a mixed-use development with retail, housing, and office space topped by a green roof park was canceled after Cupertino voters rejected Measure D on the November 2016 ballot. After obtaining community input in the planning phase, the project ran into significant push-back from citizens who wanted to freeze the site as retail-only, citing concerns about traffic and schools.

In 2018, Sand Hill proposed a revised development plan under the auspices of SB 35, which was approved by Cupertino and includes 2,402 apartments, 1.8 million square feet of office space, and 400,000 square feet of retail. Of the apartments, half of them will be affordable with no government subsidies, which would quintuple Cupertino's affordable housing stock.

Vallco was formerly anchored by the following department stores:

AMC Theatres also left the mall on March 22, 2018. Currently, the only tenants are Bowlmor Lanes and Cupertino Ice Center on the lower level and Benihana on the upper level. All of the current occupants have exterior entrances; the interior hallways of the mall have been closed to public access since late 2018.

Vallco also formerly hosted the Pacific Coast Farmers' Market in the parking lot behind J.C. Penney. The market's final day at Vallco was December 30, 2016, after which it relocated to nearby Creekside Park.

In the early 1970s, the Cupertino City Council held public hearings to consider potential locations for a regional shopping center. After determining that the city could support only one such center, the Vallco group found itself competing with another group led by orchard owner Paul Mariani Jr. In 1973, the City Council chose to locate the regional shopping center on the edge of the city and granted the necessary zoning to Vallco.

Vallco Fashion Park held its grand opening at 6:00 pm on September 1, 1976. In its first several years, the mall's main walkway was punctuated by several parks showcasing aspects of local history, ranging from apricots to Klystron tubes. Vallco was one of the largest shopping centers in Silicon Valley and soon drew customers from all over the region.
