Dragomir "Dragiša" Vasic (Serbian Cyrillic: ??????? ?????; 2 September 1885 – 20 April 1945) was a Serbian lawyer, writer and publicist who became one of the chief Chetnik ideologues during World War II.
He finished law school in Belgrade and fought with the Serbian Army during the Balkan Wars and World War I.
During the interwar period, he worked as a lawyer and represented a number of communist defendants.
He was a member of the Serbian Academy of Sciences and Arts and became a correspondent at the Academy of Fine Arts on 12 February 1934.
In 1936, he joined the Serbian Cultural Club and later became its vice-president.
He is reported to have developed connections with Soviet intelligence services during this time.
Following the Axis invasion of Yugoslavia, he joined the Chetniks and became one of the three most important members of the Central National Committee established in August 1941 by Chetnik leader Draža Mihailovic.
Vasic quickly became Mihailovic's right-hand man and remained so until 1943, when Mihailovic named Stevan Moljevic as head of the Central National Committee.
In 1945, Vasic joined Chetnik commander Pavle Ðurišic and his forces as they began withdrawing from Montenegro towards Slovenia.
In April 1945, he was captured alongside Ðurišic and other Chetnik commanders and taken to the Jasenovac concentration camp, where he was killed by the Ustaše.
