Rear Admiral Norman von Heldreich Farquhar (April 11, 1840 – July 3, 1907) was an officer in the United States Navy during the American Civil War.

[2] After graduating from the Naval Academy in June 1859,[3] he served with the Africa Squadron until September 1860 when he sailed the prize slaver Triton home to the United States.

[4] Lieutenant Farquhar spent most of the Civil War off the U.S. Atlantic coast and in the West Indies, serving in the gunboats Mystic, Sonoma and Mahaska, and the cruiser Rhode Island.

He commanded the training ship Portsmouth in 1877–78, and the steam sloops Quinnebaug and Wyoming in European waters in 1878–1881.

Farquhar was commended for his fine handling of his ship during that disastrous 1889 hurricane at Apia, Samoa, in which she and a number of other American and foreign naval vessels were lost.
