Operation Lincoln was an operation conducted by the 1st Cavalry Division west of Pleiku, lasting from 25 March to 8 April 1966, with the goal of locating suspected North Vietnamese and Viet Cong bases to disrupt any planned offensives during the monsoon season.

Following multiple inconclusive skirmishes from 25 to 29 March, American scout helicopters landed in the middle of a North Vietnamese way-station in the immediate vicinity of 1000 soldiers. American forces lost two helicopters to North Vietnamese fire, but ultimately secured the area and declared the operation success as North Vietnamese soldiers withdrew toward the Cambodian border.
