An adjustable recessed lighting fixture includes a housing which is adapted to be recessedly mounted in a wall. A base is fixedly mounted in the housing. The base has a substantially semi-spherical cavity defined therein. A casing is pivotally and receivably disposed in the cavity such that the casing is movable relative to the cavity along a semi-spherical shape of the cavity. At least one socket is disposed in the casing. The socket has a light emitting unit installed therein which is adapted for providing illumination. By manually and rotatably adjusting the casing relative to the base, a projecting direction of the light emitting unit is changed.
