No suspects have been arrested in the possible drive-by shooting reported shortly before 9 p.m. Sunday in the city's Tenderloin area, police spokeswoman Danielle Newman said.
All seven victims were taken to San Francisco General Hospital with injuries to their extremities that were not considered life-threatening, Newman said.
No descriptions of suspects or vehicles were released, and no further details were immediately available on the victims.
Yellow police tape cordoned off the crime-scene sidewalk at the corner of Turk and Taylor streets in the Tenderloin, a neighborhood where crime is high and shootings are common, but rarely with so many victims.
Police briefly reported there were eight people shot, but one later turned out to be someone who walked into the hospital with an older injury who was mistaken for a shooting victim.
