Tritium (e Graeco τρίτος ‘tertius’, nota ³
₁H aut T) est isotopus radiactivus hydrogenii elementi uno protone et duobus neutronibus in nucleo. Ita massam triplicem praebet quam hydrogenium commune, i.e. protium (¹
₁H). Vix anno 1934 a chemista Ernesto Rutherford, Marco Oliphant et Paulo Herteck e fusione deuterii inventum est, quia et in universo et in tellure rarissimum est (1 pro 10¹⁸ atomis hydrogenii). Plerumque in moleculis dihydrogenii versatur. Rutherford tritium invenit duobus deuterii nucleis fusis secundum reactionem: D + D → T + H. Hodie minus rarum est quia in reactris nuclearibus creatur.

Atomi tritii particulas beta (electrones) emittunt atque paulatim in helium-3 mutantur, semivitā duodecim annorum et triente. Helium fit secundum reactionem infrascriptam:

Aquae quoque incorporatur tritium quae tunc aqua tritiata^(en) dicitur. Illane aqua saluti nocere possit disputatur.
