Pep flags, also known as flaggies, short flags, small flags, or twirl flags, is the performing art of twirling one or two flag(s) as part of a choreographed routine. In the early 21st century, some school flag squads have implemented a third or even fourth flag in routines. This performing art is mainly prominent in Southern California high schools. It is mainly in high schools but a few are in elementary, middle school, and college/university levels.

Although pep flags has been around for many decades (and has evolved much since then), it has been gaining in popularity around the world. This particular style of pep flags has spanned out to other areas in Northern California and Nevada and has been known to have similar styles in Colorado, Florida, Georgia, Illinois, Louisiana, Massachusetts, Ohio, Pennsylvania, South Carolina, and Wisconsin. Twirling has also reached other countries such as Australia, Canada, Hungary, Japan, South America, St. Kitts, and the United Kingdom.

Depending on the place, pep flags may be classified with baton (flag baton), majorettes or precision/prop. Usually, pep flags is often associated with cheerleading, as it is one of the main aspects of school spirit: cheerleading, songleading/pom pom, mascots, and pep flags. Not to be confused with auxiliary or colorguard, pep flags is a separate discipline. However, much like other auxiliary and spirit teams, pep flags takes much hand and eye coordination, athleticism, showmanship, and overall teamwork and good sportsmanship. Many flag routines involve choreography to music, dance/cheer elements (such as kicklines, pyramid mounts, etc.), numerous combinations of twirls, flag tricks, and flag tosses (also known as exchanges).

Many schools that have a pep flag squad can generally be seen performing at school pep rallies, football games (pre-game, half-time, or even along the sideline with the cheerleaders), and cheering at other sporting events during the fall. Some may be seen marching with their school's marching band during parade season. In the Northern Hemisphere spring, teams compete in several indoor competitions against other schools. Some of the main competitions that occur are United Spirit Association (USA) Regionals and Nationals, Miss Dance Drill Team USA, and Sharp competitions, as well as smaller school-sponsored competitions throughout the Southern California area. Generally, these competitions have two separate divisions for one-flag and two-flag routines. In addition, they may also include solo, duet, and trio divisions as well.
