"The Ebola patient died during the night in the St Georg Clinic in Leipzig," it said in a brief statement.
"Despite intensive medical care and the best efforts by medical staff, the 56-year-old UN employee succumbed to the serious infection," it added.
Local health officials said last week that the patient was a Sudanese doctor who had arrived in Germany from Liberia on Thursday.
Germany has previously treated two other Ebola patients infected in Sierra Leone -- a Senegalese expert who was treated in Hamburg and released on October 4, and a Ugandan doctor now being treated in Frankfurt.
The US and UN leaders yesterday called for "more robust" international efforts to tackle Ebola after medics in Liberia demanded danger money to treat patients in what officials termed the worst health crisis of modern times.
