Sergeant Alexander Joseph Foley (February 19, 1866 – January 14, 1910) was a member of the United States Marine Corps who was awarded the United States' highest military decoration, the Medal of Honor, for having distinguished himself during the Boxer Rebellion.

The small garrison of Marines stationed in Tientsin found themselves under attack and outnumbered by the nationalists, who were determined to "drive the foreign devils" out.

In the letter which Major Regan wrote recommending the Medal of Honor, he stated the following: After serving in the Boxer Rebellion, Foley was sent to the Marine garrison located in Cavite, in the Philippine Islands.

Navy Department, No.55 Citation: In the presence of the enemy in the battle near Tientsin, China, July 13, 1900, Foley distinguished himself by meritorious conduct.

The Department of the Navy did not consider it practical at that time to transfer his body to his hometown, therefore Foley was buried in the municipal cemetery of Culebra, with flags at half mast and with full military honors.
