Nelson Ku (Chinese: 顧崇廉; 6 June 1931 – 15 January 2007) was a Taiwanese politician, diplomat and naval officer.

[9] He was strongly opposed to a 2002 proposal to acquire Kidd-class destroyers from the United States, favoring the purchase of Aegis-enabled vessels instead.

[10][11] Ku was critical of a separate plan to buy Standard SM-II missiles for over NT$40 million each.

[14][15] The next year, two members of the United States House of Representatives proposed that Taiwan send the Republic of China Marine Corps to engage in the Iraq War, a move Ku believed to be unnecessary.

[19] In 2005, he voted against an arms procurement bill that sought to fund a $480 billion purchase of eight diesel submarines along with missile batteries and military aircraft, berating the government for its dependence on the United States.
