The Catholic Worker Movement is a collection of autonomous communities founded by Dorothy Day and Peter Maurin in the United States in 1933.

Day attempted to put her words from the Catholic Worker into action through "houses of hospitality"[4] and then through a series of farms for people to live together on communes.

[11] Well over 200 communities exist today, including several in Australia, the United Kingdom, Canada, Germany, the Netherlands, Mexico, New Zealand, and Sweden.

According to co-founder Peter Maurin, the following are the beliefs of the Catholic Worker:[15] The radical philosophy of the group can be described as Christian anarchism.

[20] Author Daniel McKanan has suggested that, for a variety of reasons, Dorothy Day's perspective on family involvement in the movement was controversial.

[19] Despite these elements of conflict, families have participated in the Catholic Worker Movement through multiple avenues: some assist the houses of hospitality while others open up a "Christ room" in their homes for people in need.
