Circle of Palms Plaza, Public plaza in downtown San Jose, California, US.

Circle of Palms Plaza is a public gathering space in downtown San Jose surrounded by a ring of palm trees with California's State Seal at its center. The site is bounded by an art museum and office buildings that frame the open area.

California Historical Landmark 461 marks the site of the state's first capitol, a two-story adobe hotel built around 1830. The first legislature met there in December 1849 and again in 1850 and 1851, while San Jose served as the seat of government from 1849 to 1851. The block later held the Market Street Chinatown from 1866 to 1887 and was redeveloped as a plaza in the 1980s.

The block was home to Market Street Chinatown from 1866 until it was destroyed by arson in 1887; it was the centre of Chinese-American life in the Santa Clara Valley. The site was redeveloped into a plaza in the 1980s.

The plaza is a flat, open paved surface at ground level, with concentric bands of light and dark grey stone and no steps between the palm rows. It sits between the Fairmont San Jose Hotel, the KQED building and the San Jose Museum of Art, so it works as a short walking link through downtown. The California State Seal and the 1849 constitutional quotes are set into the concrete at the centre, where visitors stop to read them.

The plaza's concrete paving carries quotations from the 1849 constitutional convention in Monterey, where San Jose was chosen as the state capital. The seal at the center marks California Historical Landmark 461, and a plaque notes that the first capitol stood directly opposite.
