Polei Kleng Camp (also known as Camp Le Vanh, Firebase Bass, Landing Zone Bass or Polei Kleng Special Forces Camp) is a former U.S. Army and Army of the Republic of Vietnam (ARVN) base west of Kontum in the Central Highlands of Vietnam.

The base was established in June 1966 approximately 16 km west of Kontum by the 5th Special Forces Group, Detachment A-241.

In May 1972 during the Battle of Kontum after overrunning the ARVN bases at Tân Cảnh, Đắk Tô and the Firebases along Rocket Ridge the PAVN turned their attention to the base and to Ben Het Camp which blocked the avenues for attack on Kontum.

The base had been subjected to artillery fire since 24 April, but from midday on 6 May the volume of fire increased dramatically with over 500 rounds systematically destroying the base bunkers and an infantry assault by the PAVN 64th Regiment penetrated the perimeter.
