Occupy Oakland is an ongoing protest encampment located in downtown Oakland at Frank H. Ogawa Plaza in front of Oakland City Hall and Snow Park near Lake Merritt in Oakland, California. It is allied with the Occupy Wall Street movement that began in New York City on September 17, 2011, and is one of several "Occupy" protest sites in the San Francisco Bay Area. Other sites include Occupy San Francisco and Occupy San Jose.

The demonstration began on October 10, 2011. At its peak, the initial encampment consisted of about 150 tents. The two protest sites at Frank Ogawa Plaza and Snow Park were dismantled by police officers early in the morning on October 25, 2011. Later that day, the protesters tried to reclaim the sites. During clashes with police, two officers and three protesters were injured and more than a hundred people were arrested.

The next day, October 26, more than a thousand protesters gathered peacefully at Frank Ogawa Plaza. Tents were set up again on the plaza that evening. The general assembly agreed to organize a general strike for November 2.
