碲化氢是化学式为H₂Te的化合物。它是碲的氢化物中结构最简单的。

许多Te-H键的化合物都不稳定，易释放出H₂，H₂Te也是如此。

H₂Te的化学性质与硒化氢类似，都是易起反应的酸性气体，H-X-H 键角也都接近90°。

碲化氢为吸热性的化合物，放在空气中不稳定且容易被酸化形成水和碲。

2 H₂Te + O₂ → 2 H₂O + 2 Te

Hydrogen telluride (tellurane) is the inorganic compound with the formula H₂Te. The simplest hydride of tellurium, it is rarely encountered because it decomposes rapidly to its constituent elements. However, the gas can exist at very low concentrations long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations. Most compounds with Te–H bonds (tellurols) are unstable with respect to loss of H₂. H₂Te is chemically and structurally similar to hydrogen selenide, both are acidic. The H–Te–H angle is about 90°. Volatile tellurium compounds often have unpleasant odours, reminiscent of decayed leeks or garlic.
