Harry Chapman Adriance (October 27, 1864 – January 25, 1934) was a United States marine who received the Medal of Honor for his "distinguished conduct in the presence of the enemy in battle near Tientsin, China" on July 13, 1900, during the Boxer Rebellion.

Adriance returned to Cavite after his tour in China and then was transferred to the Brooklyn Navy Yard, New York, on July 20, 1902.

A contested court-martial approximately one year later regarding theft charges resulted in him receiving a bad conduct discharge from the Marine Corps and a reduction in rank to private on September 7, 1904.

[citation needed] In the late 1980s, the Marine Corps League in his hometown of Oswego initiated proceedings in an attempt to upgrade Adriance's discharge.

Citation: In the presence of the enemy during the battle near Tientsin, China, July 13, 1900, Adriance distinguished himself by meritorious conduct.
