The 2013 U.S. F2000 National Championship is a season of the U.S. F2000 National Championship, an open wheel auto racing series that is the first step in IndyCar's Road to Indy ladder. It is the fourth full season of the series since its revival in 2010.
There are two classes of competition, the premier Championship Class and the lower National Class. For this season all National Class competitors will use the Formula SCCA/FE chassis. This chassis was first allowed in the National Class in 2012. Championship Class competitors will continue to use Mazda MZR powered Van Diemen F2000 chassis with a league-specified wing package. National Class competitors were previously allowed to use Van Diemen chassis with less powerful engines than the Championship Class.
