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.
