Rubidium telluride is the inorganic compound with the formula Rb₂Te. It is a yellow-green powder that melts at either 775 °C or 880 °C (two different values have been reported). It is an obscure material of minor academic interest.^[1]

Like other alkali metal chalcogenides, Rb₂Te is prepared from the elements in liquid ammonia.^[2]

Rubidium telluride is used in some space-based UV detectors.^{[citation needed]}

The compound has several polymorphs. At room temperature, ω-Rb₂Te is a metastable antiflourite type structure, and transforms to α-Rb₂Te upon heating, which is a PbCl₂ type structure.^[3]
