The Venturers were a group of sailors who explored Middle-earth led by the son and heir of Tar-Meneldur, Tar-Aldarion.

They founded a harbour at the mouth of the Gwathló that survived into the third age. The harbour was originally called Vinyalondë and in the Third Age, what remained was called the port of Lond Daer.
