"Aid to the Church in Need" is an international pastoral aid organization of the Catholic Church, which yearly offers financial support to between 5,000 and 6,000 projects worldwide. ACN helps the poor and persecuted churches with prayer, pastoral relief and material assistance.

Following a 1984 decree of the Vatican Congregation for the Clergy, "Aid to the Church in Need" is recognized by the Catholic Church as a "universal public association of faithful".

ACN raised 2008 Euro 82 million. The money distributed in 137 different countries around the world comes entirely from donations. ACN receives no public or official Church monies whatsoever, but relies on the generosity of more than 700,000 individual benefactors around the world.
