UAAR, or Unione degli Atei e degli Agnostici Razionalisti, is a social promotion association that focuses on the rights of non-believers, secularism, and rationality. With their headquarters in Rome, Italy, UAAR offers a range of products and services aimed at promoting these values. Their activities include various campaigns, events, and informational initiatives on topics such as atheism, religion, and secularism.

They also provide services like non-religious ceremonies, known as Cerimonie Uniche, conducted by trained secular celebrants. Additionally, UAAR publishes a bi-monthly magazine called Nessun Dogma, which explores themes like rights, ethics, philosophy, politics, and science from a secular-humanistic perspective. They also have a book project that publishes texts with a secular-rationalist approach.

UAAR is dedicated to quantifying the costs associated with the Catholic Church in Italy, shedding light on its financial resources and tax privileges through their ongoing investigation. To support their mission, UAAR operates an online shop where you can find their magazine, books, and various merchandise. Overall, UAAR strives to create a society that respects the rights and values of non-believers, promoting rationality and secularism as the guiding principles
