State Route 207 (SR 207) is a state highway in the U.S. state of California in Alpine County. It connects State Route 4 to Mount Reba.

The route begins at State Route 4 as a two-lane road, and heads north to its northern terminus at Mount Reba, where it expands to make way for the Bear Valley parking lot. Because SR 207 is the only way to access the Bear Valley Ski Resort, the state highway has more traffic during winter than when it isn't snowing in the mountains. The route totals about a mile. After the intersection with State Route 207, State Route 4 quickly becomes a one-lane highway.

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, and do not necessarily reflect current mileage. The entire route is in Alpine County.
