The Moose is a fraternal and service organization founded in 1888, combining nearly 800,000 men in approximately 1,800 Lodges of the Loyal Order of Moose and more than 400,000 members in roughly 1,600 Chapters of the Women of the Moose, in 49 states and four Canadian provinces, plus Great Britain and Bermuda.

The men and women of the Moose support the operation of Mooseheart Child City & School, a 1,000-acre community for children and teens in need, located 40 miles west of Chicago; and Moosehaven, a 72-acre retirement community for its members near Jacksonville, FL. 

 Moose Lodges conduct between $70 million and $100 million worth of community service (counting monetary donations, volunteer hours worked, and miles driven) annually.  Additionally, the Loyal Order of Moose conducts numerous sports and recreational programs, in local Lodges and Family Centers, in the majority of 44 State and Provincial Associations, and on a fraternity-wide basis.
