Junior varsity (often called "JV") players are the members of a team who are not the main players in a competition (such as any football, basketball, or baseball game), usually at the high school level–– and formerly at the collegiate level–– in the United States. The main players comprise the varsity team. Although the intensity of the JV team may vary from place to place, most junior varsity teams consist of players who are in their freshman and sophomore years in school, though occasionally upperclassmen may play on JV teams. For this reason, junior varsity teams are also often called freshman/sophomore teams. Especially skilled or physically mature freshmen and sophomores may compete at the varsity level. Some private school associations may permit very skilled seventh- or eighth-graders to compete on varsity teams. At larger schools, there may be two junior varsity teams for some sports, with a lower-level team typically consisting only of freshmen.

Some teams require participation on a junior varsity team before being eligible to try out for a varsity team. These players can provide the varsity team with extra depth, with their service as back-up players. The NCAA previously prohibited true freshmen from playing varsity college football and basketball; as a result, numerous junior-varsity "freshmen teams" appeared on many major college campuses. The NCAA repealed this limitation in 1972; to the extent that junior varsity teams exist at the college level, many are classified as club squads. Many sports teams have assistant coaches responsible for developing the talent of junior varsity players. When they play A coach may call on one or more junior varsity players during a varsity game, especially when a varsity player is injured, is not performing well, or (because
