The invention provides a frame folding mechanism, a frame locking mechanism, a backrest unlocking mechanism and a stroller. A handle, a front foot, a seat portion and a linking member of the frame folding mechanism form a planar linkage mechanism. The handle and the front foot can be driven to rotate and fold toward a rear foot, so as to drive the seat portion to rotate and fold. The frame locking mechanism can drive a sliding member and a frame expansion locking member to slide by an unlock driving mechanism, such that the frame expansion locking member disengages from a handle locking hole and a front foot locking hole to unlock a frame. The backrest unlocking mechanism has a backrest locking member. The unlock driving mechanism can drive the backrest locking member to slide, such that the backrest locking member disengages from a backrest portion to unlock the backrest portion.
