A rocking chair includes a fixed base having a base portion located on the ground. The base portion includes front and rear sides spaced in a rocking direction. A connecting frame extends upright from the base portion and has a receiving space receiving a rocking mechanism. The rocking mechanism includes a bottom plate, a strut, and front and rear rocking members. The strut extends upright from the bottom plate and is fixed to a seat. Upper ends of the front and rear rocking members are pivotably connected to the connecting frame. Lower ends of the front and rear rocking members are pivotably connected to front and rear ends of the bottom plate. The rocking mechanism is rockable in the receiving space in the rocking direction relative to the fixed base. A positioning mechanism controls the rocking mechanism to be in a rockable state or a positioned state.
