The Russian bar (or Russian barre) is a circus act which combines the gymnastic skills of the balance beam, the rebound tempo skills of trampoline and the swing handstands skills of the uneven bars and the parallel bars. The bar (or barre) itself is a flexible vaulting pole around 4 meters long. At the present heights, aerial skills such as triple, "fliphess" (double twisting doubles{fact}) and "trephisis" (triple twisting double{fact}) somersaults are possible.

The Russian bar act requires acrobats to be highly skilled in tumbling and have experience with the trampoline and/or sports acrobats. To perform, the act must collaborate on many levels. Additionally, the act requires not only physical skill, but psychological and communicative skills as well.
