A cart handle and a baby cart in which cart handle includes a fixed member; a handle body rotatable relative to the fixed member; an engagement part having a first portion that non-rotatably engages the handle body and slidably engages the handle body, and having a second portion that non-rotatably engages the fixed member; and an operation part that is actuated to alternately displace the engagement part to an unlocked position, wherein the second portion is not in engagement with the fixed member, thereby permitting rotation of the handle body relative to the fixed member, and displace the engagement part to a locked position, wherein the second portion engages the fixed member, thereby preventing rotation of the handle body relative to the fixed member.
