Lieutenant General Mweukefina Kulaumone Jerobeam Dimo Hamaambo (27 October 1932 – 8 September 2002) was a Namibian military commander in both the Namibian War of Independence as a SWAPO member and in independent Namibia as the Chief of Defence in the Namibia Defence Force.

He became the second commander of the People's Liberation Army of Namibia (PLAN) in 1967 after the death of Tobias Hainyeko and held the position until independence was gained in 1990.

After receiving some education in area schools, Hamaambo went to work outside of Ovamboland as a contract labourer on a White owned farm as well as a domestic worker, at a cannery in Walvis Bay and eventually in the gold mines of Johannesburg, South Africa.

Hamaambo eventually returned to Namibia and joined the Ovamboland People's Organization (OPO), a predecessor of the SWAPO, at Walvis Bay in 1959.

In 1974 the soldiers led by Hamaambo started using Cassinga, an abandoned Angolan iron ore mine, as a stopover point for a few weeks They soon thereafter occupied the place.
