# USL Championship 2021

La USL Championship 2021 è la dodicesima edizione della seconda divisione del campionato statunitense di calcio.
In questa stagione alla USL Championship, rispetto alla stagione scorsa, si aggiunge un club, il Oakland Roots Sports Club.

## Formula

Come la scorse stagioni le squadre sono suddivise in due Conference, la Eastern e la Western e ogni club si affronta due volte, una volta in casa e una fuori, ogni altro club appartenente alla propria conference. Le prime 7 classificate di ogni conference parteciperanno ai playoffs, con la vincente di ogni conference che salterà il primo turno accedendo direttamente al secondo.
