Umkomaas Commando was a light infantry regiment of the South African Army. It formed part of the South African Army Infantry Formation as well as the South African Territorial Reserve.

Umkomaas Commando was activated when it inherited the urban members of the Pietermaritzburg Rifle Commando in 1963.

Initially, the Umkomaas Commando was headquartered in Ixopo under Kmdt J.R.Guy. It consisted of 3 companies with A Company being based at the Drill Hall in Pietermaritzburg, B Company based in Eston-Mid Illovo and C Company based in Ixopo.

Umkomaas Commando shared close affinity with Natalia Regiment. Its original HQ (post 1989) was in Richmond where it shared accommodation with Group 9 in the Old Gaol Building.

The unit was later transferred to Pietermaritzburg and allocated its own HQ in the Oribi Village.

By July 1981 the unit moved back to Richmond, but by 1991 it had returned to the Oribi Village in Pietermaritzburg.

The unit held annual training camps and maintained a rifle shooting range on the farm Dawn Valley near Ixopo from 1963 to 1968, and near Shongweni and Hammarsdal from 1969 to 1975. From 1976 the unit deployed a company to South West Africa for border duty.

Umkomaas Commando provided quick reaction patrols in support of the South African Police during unrest in the Natal Midlands. By 1979 the units area of responsibility had changed and new borders set.
