Disclosed are tent frames and tents. A tent frame includes first and second top poles, first and second connectors, and a locking mechanism. Each of the first and second top poles has a first end portion and a second end portion. The first connector is fixedly coupled to the first end portion of the first top pole, and slidably coupled to and movable along the second pole. The second connector is fixedly coupled to the first end portion of the second top pole, and slidably coupled to and movable along the first top pole. The locking mechanism selectively restricts the first and second top poles from moving with respect to each other.
