The Loyal Order of Moose is a fraternal and service organization founded in 1888, with nearly 1 million men in roughly 2,000 Lodges, in all 50 states and four Canadian provinces, plus Great Britain and Bermuda.

Along with other units of Moose International, the Loyal Order of Moose supports 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 63-acre retirement community for its members near Jacksonville, FL. Additionally, Moose Lodges conduct approximately $50 million worth of community service (counting monetary donations and volunteer hours worked) 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.
