Goswin, Bishop of Poznan was a 12th-century Polish bishop, whose death was reported in the obituary of the Abbey of St. Vincent under the daily date 5 April.
His diocese is not known, but it is presumed he was a Bishop of Poznań.
[1] In the catalogue of Bishops of Poznań there is a large gap from 1112AD, when the bishop was Pavel, until 1146AD, when Bogufał was bishop.
Goswin could therefore have been bishop between Paul and Bogufał.
