Erwin Tiebel (born 10 November 1903) was a German lawyer. After the Nazis took power he joined the Leipzig chapter of the party in April 1933. During the late 1930s he began working for the security services. His involvement became progressively more time consuming and after 1943 he restricted his law work to existing cases. That year he was recruited into "Amt VI" (literally "Office 6"), the department in Berlin that dealt with political foreign intelligence. He worked on "commercial matters", especially with regard to "currency transactions in foreign countries". Switzerland was a particular focus, though plans that he should himself be posted to Switzerland came to nothing.
