The Polish National Union of America, also known as PNU or Spojnia, is a not-for-profit fraternal benefit society which provides life insurance protection, annuities, retirement plans and numerous fraternal benefits to its membership.

The late Prime Bishop Franciszek Hodur organized the Polish National Union of America in 1908, eleven years after the organization of the Polish National Catholic Church. Since its inception the Polish National Union served the people in America as well as in Poland. One of the initial purposes of Spojnia was to help people belonging to the Polish National Catholic Church and others who shared in the organization's goal to achieve financial security. This action brought about an important idea to promote brotherly love and to maintain a sense of identity.

Headquartered in Scranton Pennsylvania since 1908, the Polish National Union of America has lived up to Bishop Hodur's high standards by providing material and spiritual security to the members and friends of the Polish National Catholic Church.This spirit of cooperation between Spojnia's leaders and members brought about the means, the force, and the responsibilities of deeds to meet the challenges of today.

From the signing of its first member, John Drwal in 1908, the Polish National Union of America has remained true to its principles and has grown in membership over the years to nearly 25,000 members, making the Polish National Union of America one of the largest fraternal organizations in America.
