Woodmen of the World is a fraternal organization in the United States. The organization was founded in 1890 in Omaha, Nebraska by Joseph Cullen Root. Root had earlier founded another fraternal organization known as Modern Woodmen.

Originally, when a member died, a hat would be passed to provide assistance to the member's family. Later, the organization began selling life insurance to its members.

Along with providing life insurance protection, members are eligible for benefits. These include participation in a youth program, disaster relief assistance and monetary support for members' orphaned children.

There are approximately 2,000 community-based Woodmen lodges throughout the nation. Lodges conduct volunteer, patriotic and charitable activities that benefit individuals and communities.

Woodmen of the World is one of the leading presenters of U.S. flags to school and non-profit groups. Woodmen lodges have presented more than 1.4 million U.S. flags over the past 60 years. To dedicate the victims of the September 11th terrorist attacks they placed two flags on the eastern side and western side of the building in 2006. Both of these flags were 50 by 100 foot.

One of the most enduring physical legacies of the organization may be the number of distinctive headstones erected in the shape of a tree stump. This was an early benefit of Woodmen membership, and the headstones can be found in cemeteries across the nation.

Some have claimed an initiation ritual (for those who refused participation) at the headquarters involves or did for some time involve bowing down to a tree stump monument on one of the top floors and has been compared to other fraternal initiation rites.
