Jakub of Żnin () was an early archbishop of Gniezno in Poland.Jakub ze Znina Archidiecezja Gniesnienska Website He was archbishop from c. 1124 until 1148.Metropolitan Archdiocese of Gniezno at GCatholic.org

Although the twelfth century was a formative time for the Polish state, the historical records of the time are sparse and there is much that is not known about him.

It was during his time as Bishop that Innocent II issues a bull giving the metropolitan power over Poland to the Archbishopric of Magdeburg. This was annulled in 1136 when Innocent II restored as Gniezno with archbishop authority.

His death was recorded in the Lubiński obituary on the day of 23 September. On 7 July 1136 Pope Innocent II granted Archbishop Jacob twenty-nine villages in Pałuki and the town of Żnin, which also became property of the Roman Catholic Church.
