San Francisco 49'ers 

The Niners are historically one of the most succesful American Football teams with 5 Superbowl wins.

Over the years they have played at Kezar Stadium (at the edge of Golden Gate Park), at Candlestick Park but now they play 38 miles south of the city in Santa Clara (Levi's Stadium).

Golden State Warriors

The reigning NBA champions, this Warriors team will go down as one of the best in history. The main stars Steph Curry, Klay Thompson and Draymond Green have won 4 championships in recent years and are still hunting for more. They relocated back to San Francisco from Oakland recently and now play at the Chase Center.

San Francisco Giants

Playing next to the Bay at Oracle Park, seeing the Giants is quite the experience. Having won the World Series championship 8 times (including 2010, 2012 & 2014), the Giants are one of the oldest and most succesful sports teams in the country.
