Mazda Raceway Laguna Seca (previously known as Laguna Seca Raceway) is a paved road racing track in central California used for both auto racing and motorcycle racing, originally constructed in 1957 near Monterey, California, USA.

The name Laguna Seca is Spanish for "dry lagoon".  The area where the track is was originally a lake.  The course was originally built around the lake, which has since dried up entirely.  An artificial pond has since been added.
