The American Legion
Headquarters Overview
The American Legion is the nation’s largest wartime veterans service organization. While the organization maintains a significant legislative presence in Washington, D.C., its official National Headquarters is located in Indianapolis, Indiana.
Dual-Office Structure:
- National Headquarters (Indianapolis, IN): The administrative hub of the organization. It houses the National Commander’s office, internal affairs, membership processing, and the American Legion Library and Museum.
- Washington Office (Washington, D.C.): Located at 1608 K Street NW, this office focuses on legislative advocacy, veterans’ benefits, and national security policy. It serves as the base for the Legion’s interactions with the White House and Congress.
Mission & The “Four Pillars”
Chartered by Congress in 1919, the American Legion focuses its service and advocacy on four founding pillars:
- Veterans Affairs & Rehabilitation: Advocating for proper healthcare, processing VA claims, and ensuring veterans receive earned benefits.
- National Security: Supporting a strong national defense and quality of life for active-duty troops.
- Americanism: Promoting patriotism and good citizenship through flag education and community service.
- Children & Youth: Sponsoring programs that ensure the well-being of America’s youth.
Key Programs
The American Legion sponsors thousands of local posts and several nationally recognized programs, including:
- American Legion Baseball: One of the country’s most prominent amateur baseball leagues.
- Boys State & Boys Nation: A premier participatory government instruction program for high school students.
- Operation Comfort Warriors: Providing non-medical comfort items to recovering wounded warriors.
