Baroness Sigrid von Laffert (18 January 1916 – 8 September 2002) was a German aristocrat.
She accompanied Adolf Hitler to the German Opera House in Berlin, Germany in December 1935.
She was rumored to be a romantic companion of Hitler during the time he neglected his companion Eva Braun, between early March and late May 1935.
Von Laffert was also a relative of Viktoria von Dirksen, the widow of Willibald von Dirksen, secret legations counsel for Kaiser Wilhelm.
Von Laffert was a member of the Alliance of German Maidens (Bund Deutscher Mädel, or BDM) during the year 1932-1933.
This was the girls' branch of the Hitler Youth.
A blonde woman, she was considered among the most beautiful women around Hitler.
She was invited by him to various festive events.
Among these was a National Day of Celebration of the German People, held on May 1, 1934.
The occasion was staged as a large propaganda public display at Tempelhof Field.
Von Laffert continued to appear at important Nazi government functions as late as March 1939.
In 1939 she was invited to a state dinner in the Chancellor's home.
It is plausible that Eva Braun was forbidden to appear on such occasions.
