Radio Télévision Libre des Mille Collines

Radio Télévision Libre des Mille Collines (RTLM) (Kinyarwanda: Radiyo yigenga y'imisozi igihumbi) was a Rwandan radio station which broadcast from July 8, 1993, to July 31, 1994. It played a significant role in inciting the Rwandan genocide that took place from April to July 1994, and has been described by some scholars as having been a de facto arm of the Hutu government.

The station's name is French for "Free Radio and Television of the Thousand Hills", deriving from the description of Rwanda as "Land of a Thousand Hills". It received support from the government-controlled Radio Rwanda, which initially allowed it to transmit using their equipment.

Widely listened to by the general population, it projected hate propaganda against Tutsis, moderate Hutus, Belgians, and the United Nations Mission Assistant to Rwanda (UNAMIR). It is regarded by many Rwandan citizens (a view also shared and expressed by the UN war crimes tribunal) as having played a crucial role in creating the atmosphere of charged racial hostility that allowed the genocide against Tutsis in Rwanda to occur. A working paper published at Harvard University found that RTLM broadcasts were an important part of the process of mobilising the population, which complemented the mandatory Umuganda meetings. RTLM has been described as "radio genocide", "death by radio" and "the soundtrack to genocide".
