A handle height adjusting mechanism includes: a coupling member disposed on a handle tube of a stroller; an actuating member disposed movably on the handle tube, and coupled to the coupling member for driving movement thereof; an engaging member connected to the coupling member; and a resilient member coupled to the coupling member for biasing the coupling member to a first position, where the engaging member engages the selected positioning hole to arrest movement of the handle tube relative to the frame tube. The actuating member is operable to move the coupling member to a second position against biasing action of the resilient member, such that the engaging member is removed from the selected positioning hole so as to permit movement of the handle tube relative to the frame tube.
