The World Union for Progressive Judaism (WUPJ), established in London in 1926, is the international network of the Reform, Liberal, Progressive and Reconstructionist movements, serving 1,200 congregations with 1.8 million members in more than 50 countries.

Headquartered in Jerusalem, the WUPJ represents the largest body of Jews in the world who seek a traditional yet contemporary expression of their Jewish spiritual, cultural and religious identity. The WUPJ supports the Progressive Zionist Youth Movement, Netzer Olami, and the TaMaR Progressive Young Adult Movement.
