Rubidium telluride or Rb2Te is a chemical compound of the elements rubidium and tellurium. It is a difficult compound to synthesize; this is in part due to the instability of the substance(Stöwe). The CAS registry number is [12210-70-7].

Rubidium telluride is prepared from the elements in liquid ammonia. It is a yellow-green powder that melts congruently at 775 °C (or 880 °C as two different values are reported).

This compound is very rare and there for are a limited number of suppliers. Pfaltz and Bauer sells Rb2Te for approximately 560 USD per gram (2006).
