Radoje Knežević (Serbian Cyrillic: Радоје Кнежевић; 20 August 1901 – 22 June 1983) was a key member of the group that organised the Yugoslav coup d'état of 27 March 1941 that deposed the regency of Prince Paul, Dr. Radenko Stanković and Dr. Ivo Perović, along with the government of Prime Minister Dragiša Cvetković.

He remained in exile after the war, was sentenced to 10 years imprisonment with hard labour in absentia during the Belgrade Process conducted by the country's newly-established communist authorities, and emigrated to Canada where he lived until his death in 1983.

[7] In early 1942, the government-in-exile led by Simović was split along ethnic lines, with Knežević and his brother Živan forming part of an inner circle of anti-Simović advisers around King Peter, known as the "League of Majors".

[9] The group of younger officers wanted to ensure that they would have a "direct share in power" with the Chetnik leader Brigadier General Draža Mihailović in a Chetnik-dominated government after the war had ended.

On 5 March 1942, his first day in the role, Lozić asked the British to remove Mirković and his supporters from Cairo and hand over several others, including Popović, to Yugoslav authorities for court martial on charges of mutiny.

The "Scandal of Cairo" constituted at least a partial victory for the Jovanović government and "League of Majors" but the whole affair damaged the relationship of the government-in-exile with the Western Allies and negatively affected potential aid to Mihailović.

[12] The British ambassador to the Yugoslav government-in-exile from July 1941 until August 1943, George William Rendel, was very conscious of the power wielded by Knežević, noting that he was "by no means working in harmony with the government".

[13] A wartime British intelligence handbook described the Knežević brothers as "the most powerful forces in the exiled Yugoslav Government and the most instrumental in carrying through its chauvinistic Great Serb and anti-Partisan policy".

While Cvetković issued two strong denials in the historical journal Dokumenti o Jugoslaviji, and stated that seizing Salonika had never been on the agenda of the Yugoslav government, his latter statement was not true.
