Yes indeed, the Sun rotates on its axis once approximately 27 days. This rotation was first detected by observing sunspots movement. Sun's rotation axis is tilted about 25.7 degrees from the axis of Earth's orbit and thus we see more of the Sun's north pole in September of each year, and over the Sun's south pole in March.
Since the Sun is a ball of gas, it does not have to rotate rigidly as do solid planets and satellites. In fact, the equatorial regions of the Sun rotates faster (taking them only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential revolution" is an area of actual research in solar astronomy.
