Bernard of Wąbrzeźno (Polish: Bernard z Wąbrzeźna, pronounced [ˈbɛrnard zvɔmˈbʐɛʑna], born Błażej Pęcharek, pronounced [ˈbwaʐɛj pɛ̃ˈxarɛk]; 3 February 1575 – 2 June 1603) was a Roman Catholic priest and a Benedictine monk from the Benedictine Abbey in Lubiń, Poland.

A legend associated with Bernard was that he performed a miracle to restore water to the depleted well in the town of Grodzisk Wielkopolski, Poland.

[1] He was born in early 1575 in Wąbrzeźno, in the province of Royal Prussia in the Polish–Lithuanian Commonwealth, although the exact date is not known because a fire destroyed the town's church records in about 1751.

[2] His date of birth is estimated to be within a few days of 3 February, based on statements of his older sister Elizabeth who testified under oath in 1645 about his age and baptism.

[1][5] Starting in the 1730s, the Archbishop of Poznań began collecting materials to produce biographies and testimonies of the miracles of Bernard.

[5] However, many of the Vatican archives were lost during the occupation of Rome by Napoleon's Army in the late 1700s, including some of the testimonies of the bishops of Poznań.
