A folding frame and a folding vehicle are provided. The folding frame includes a cross beam, a pillar, and a supporting column; the cross beam includes a front beam and a rear beam. A rear-end bottom of the front beam is rotationally connected to a front-end bottom of the rear beam so that the two can be vertically folded. An angle between a rotational axis of the front beam and a central axis of the rear beam is an acute angle. The supporting column includes a front column and a rear column, the front column is inserted in the front beam to cooperate, the front column is rotationally connected to the rear column, and the rear column is rotationally connected to the pillar. The front beam and the rear beam are vertically folded, and then they will not spontaneously rotate to fold in the riding process, possessing relatively good reliability. A front end of the front column is inserted in the front beam, and supports below the front beam, thus the cross beam can be positioned in the unfolded state and will not be flipped downwards. The cross beam, the pillar, and the supporting column define a triangular shape, which can ensure the stability of the whole frame. When the rear column and the front column are rotated, the front column and the rear column can be bent relatively, the front column can be pulled out from the front beam, and the front beam is flipped downwards, then the frame can be folded, being simple in operation and convenient in use.
