John F. D. Spence (2 October 1875 – 20 February 1946) was a British sailing competitor at the 1908 Summer Olympics.

[1][2][3] Sources also give his name as James Fleming Drever Spence.

[4][5] He was a crew member on the Mouchette which finished second of two teams competing in the 12 metre class.

[1][6] At the time, only the helmsman and mate were awarded silver medals, while the crew received bronze medals.

[1] However, Spence is credited as having received a silver medal in the official Olympic database.
