Świdger (died 1156) was a semi-legendary bishop of Kruszwice.
Jan Długosz in his chronicle ascribes to him the consecration of the Norbertine monastery in Strzelno on March 16, 1133, but there is no consensus on the reliability of this entry.
[4] In any case, in the bull of Innocent II from June 4, 1133, is the first reference of the diocese of Kujawy, which allows us to assume that Swidger was actually a bishop of this diocese this year.
The exact date of Swidger's death is unknown.
His successor Warner is certified for the first time on April 4, 1148, in the protection bullave of Eugene III.
