Mark Lambert Bristol (April 17, 1868 – May 13, 1939) was a rear admiral in the United States Navy.

During the Spanish–American War, he served aboard the battleship USS Texas and participated in the Battle of Santiago de Cuba.

His correspondence and other documents that he gathered are often cited during discussions on numerous events of that era, including Turkish-Armenian relations in which he played a significant role in his opposition to Armenian aspirations and American involvement in assuming a mandate in Armenia.

Topics from the period include racial and religious conflicts in the Near East; the Great Fire of Smyrna; Allied activities in pursuit of special interests, mandates, and empire; the decline of the Ottoman Empire; and the rise of Mustafa Kemal and the Turkish National Movement, which led to the founding of modern Turkey.

Bristol served as chairman of the General Board of the United States Navy from 1930 to 1932 and died on May 13, 1939.
