Elijah Sterling Clack Robertson (1820–1879) was an early white settler in Robertson's Colony in Texas. His father was the colony's founder Sterling C. Robertson. Brought to Texas to learn the Spanish language, he translated for both Robertson's Colony and later the Texas General Land Office. He practiced law in Milam County. Robertson was a postmaster for the Republic of Texas, and the leader of a volunteer group who aided Alexander Somervell in border disputes.
