Gideon Lane Soule (/soʊl/ SOHL; July 25, 1796 – May 28, 1879) was an American educator, and the third principal of Phillips Exeter Academy.

He was descended from George Soule, a Mayflower passenger, and John Wheelwright, the founder of the town of Exeter, New Hampshire.

At a young age, he left school to work as an errand boy for Jacob Abbot, who helped him attain admission to Phillips Exeter in 1813.

Augustus Soule went on to become a New York Supreme Court Judge.

Soule Hall, one of the oldest dormitories on campus, is named for Gideon Lane Soule, as was the Gideon Lane Soule Literary Society, which merged with the Golden Branch Literary Society to form what is now the Daniel Webster Debate Society at Exeter.
