The Helion Lodge is a historic structure in Huntsville, Alabama. It is the oldest Masonic lodge in the state of Alabama, being built in 1824.

The Helion Lodge?s growth can be attested, however, to the further growth of Huntsville, which took place after the World War II. Around this time, the Redstone Arsenal and the Marshall Spaceflight was built in the quiet little town, which attracted new settlers. More members moved to town, most notable of which are Mayor Joe W. Davis and Senator John Sparkman. The membership grew, which called for the need of a new lodge. Two new Lodges were formed, with the Helion Lodge as their mother lodge.

The Helion Lodge is now a part of the Twickenham Historic District.
