John Misiaszek (June 20, 1903 – 1973) was a bishop of the Polish National Catholic Church.
He was a major figure in encouraging the use of English in the worship of the PNCC.
Misiaszek resigned in 1956 after his marriage to a divorced woman.
The Great Council of the Polish National Catholic Church met in Buffalo in September 1956 to examine this matter, and Bishop Misiaszek was succeeded initially by Leon Grochowski.
