Robert Fulwood Ligon (December 16, 1823 – October 11, 1901) was the fourth Lieutenant Governor of Alabama.

A Democrat, Ligon served Governor George S. Houston of the same political party from 1874 to 1876.

Ligon began his education in the local schools of Watkinsville and later attended the University of Georgia.

Although Ligon served his full two-year term as Lieutenant Governor, the position was eliminated in 1875 and would not be reestablished until adoption of the Alabama Constitution in 1901.
