1918 USA Indoor Track and Field Championships

The 1918 USA Indoor Track and Field Championships were organized by the Amateur Athletic Union (AAU) and served as the national championships in indoor track and field for the United States.

The men's championships were held at the 22nd Regiment Armory in New York City, New York, and they took place March 18. Women's championships were not officially held until 1927.

At the championships, Joie Ray equalled the world record for 1000 yards. He beat Mike Devanney by 25 yards. Ray split the half-mile in 1:57 during that race, which was considered a feature of the championships. It was the last time that a 5 miles race was held at the indoor championships.
