David Rogerson Williams (March 8, 1776 – November 17, 1830) was a representative in the United States Congress and the 45th governor of South Carolina from 1814 to 1816.

Born in Darlington County in the Province of South Carolina, Williams was educated at schools in Wrentham, Massachusetts, and attended Rhode Island College until he withdrew in 1795.

In general, Williams was a political maverick who stressed the need for limited government while also having greater accountability to the voters.

As an ardent Nationalist, Williams left the House in 1813 to participate in the War of 1812 and was appointed by President James Madison as a brigadier general in the U.S. Army.

He was elected in 1824 to the South Carolina Senate and served until his accidental death while superintending the construction of a bridge over Lynchs Creek on November 17, 1830.
