Okatie (pronounced "OH-kuh-tee") is an unincorporated suburban community west of Hilton Head Island, located in Beaufort and Jasper counties, in the Lowcountry of South Carolina.

Okatie has experienced predominantly low-density residential development since the 1990s, including Sun City Hilton Head, Riverbend, and Oldfield.

Additional commercial and low intensity industrial development have also occurred, primarily in the Jasper County sections of Okatie.

This development pattern has resulted in concerns over water quality and loss of forest habitat for wildlife.

Previous efforts to incorporate the community have been unsuccessful, due in part to conflicting opinions on the future of growth and development in the area.
