A bedhead frame and a bed frame structure having the bedhead frame are provided. The bedhead frame includes two vertical rods arranged symmetrically and at least one horizontal rod connected between the two vertical rods. Each of the vertical rods is an L-shaped structure. The horizontal rod and the vertical rods of the bedhead frame are detachable, which can be transported or stored conveniently. In particular, the vertical rods of the bedhead frame employ an L-shaped structure. When a mattress is installed to the bed frame structure having the bedhead frame, both sides of the mattress are just between upright sides and horizontal sides of the two vertical rods, thereby preventing the mattress from shifting.
