A stroller frame (100) includes a front leg (10), a bottom tube (30), a rear leg (20), an upper support member (40) and a lower support member (50). The front leg (10), the bottom tube (30), the lower support member (50) and the upper support member (40) are pivotally connected to each other to form a four-bar linkage structure. The rear leg (20) is connected to an end of the bottom tube (30). A lock mechanism (60) is disposed at a pivot joint between the upper support member (40) and the lower support member (50). The lock mechanism (60) is able to lock the upper support member (40) and the lower support member (50) at an expanded angle, such that the front leg (10) is able to be expanded with respect to the bottom tube (30). The lock mechanism (60) is unlocked to release the upper support member (40) and the lower support member (50), such that the front leg (10) is able to be folded with respect to the bottom tube (30).
