A baby stroller frame comprises a front frame, a pair of rear leg tube, and a guiding frame. The front frame connects a front wheel. The pair of rear leg tube, each has an upper end pivotally connected with the front frame, a lower end connected a rear wheel, and a joint connected with a sliding sleeve. The guiding frame has a front end pivotally connected to the front frame, and a pair of connecting arms slidably connected with the sliding sleeve. By simply rotating of the guiding frame, the sliding sleeve would carry the pair of rear leg tubes to rotate and close to the front frame. As the structure of such a stroller frame is being simplified, it would much lower the manufacture cost of a baby stroller frame and provide a new and smooth operation for a user.
