The Combahee Bank Lighthouse is a former lighthouse in St. Helena Sound on the border of Beaufort and Colleton Counties in South Carolina.

It was near the location of the current automated light, which is on a dolphin.

Due to settling, the daymark was replaced with a lighted buoy in 1913.

Most of the old structure was removed in 1925 by a buoy tender's derrick.
