Siegen-Wittgenstein was created in 1949, then known as Siegen-Stadt und -Land – Wittgenstein. From 1965 through 1976, it was named Siegen – Wittgenstein. From 1980 through 1998, it was named Siegen-Wittgenstein I. It acquired its current name in the 2002 election.

Originally, the constituency comprised the independent city of Siegen as well as the districts of Landkreis Siegen and Wittgenstein.
