Dieter Eilts (born 13 December 1964) is a German former professional footballer who played as a midfielder.
His nickname was the Alemão of East Frisia, due to his resemblance to Brazilian midfielder Alemão.
The word Alemão means "German" in Portuguese (but then again, the Brazilian player earned his nickname precisely because of his blond "German" appearance).
After retiring as a player, he began a managerial career and also worked for SV Werder Bremen as director of the football academy.
