The Danie Theron Medal, post-nominal letters DTM, is a military decoration which was instituted by the Republic of South Africa in 1970 and which was in use until 1993.

[2][3][4][5][6] The Danie Theron Medal, post-nominal letters DTM, was instituted by the State President in 1970.

[2][3] The position of the Danie Theron Medal in the official order of precedence was revised three times after 1975, to accommodate the inclusion or institution of new decorations and medals, first upon the integration into the South African National Defence Force on 27 April 1994, again in April 1996, when decorations and medals were belatedly instituted for the two former non-statutory forces, the Azanian People's Liberation Army and Umkhonto we Sizwe, and finally upon the institution of a new set of awards on 27 April 2003.

The Danie Theron Medal is a medallion struck in silver, 38 millimetres in diameter and 3 millimetres thick, depicting an eagle raising its wings on the obverse, inscribed "DANIE THERON" around the perimeter at the top and "MEDALJE • MEDAL" at the bottom.

The green and yellow colours have their origin in the ribbon colours of the three awards which were belatedly instituted in 1920, as retrospective awards for Boer veteran officers and men of the Second Boer War of 1899–1902, the Dekoratie voor Trouwe Dienst, the Medalje voor de Anglo-Boere Oorlog and the Lint voor Verwonding.
