The Portavant Mound (also known as the Portavant Mound Site or Snead Island Temple Mound or Portavant Indian Mound) is an archaeological site on Snead Island, just west of Palmetto, Florida. On December 23, 1994, it was added to the U.S. National Register of Historic Places. The Portavant Mound site has been the target of a stabilization project to protect the mounds from damage from river erosion, looting, foot traffic, and exotic vegetation.
