A central bidirectional rotation locking mechanism for a folding tent includes a lock rod, an upper lock plate, and a lower lock plate assembly. The lower lock plate assembly includes a first lower plate, an unlocking plate, and a second lower plate. An elastic locking member and an unlocking mechanism used to control the elastic locking member to perform locking are disposed in the unlocking plate. The elastic locking member is used to lock the lock rod, and the unlocking plate is capable of bidirectional rotation. When the unlocking plate rotates, the unlocking mechanism is enabled to unlock the elastic locking member and the lock rod.
