Le rubidium est l'élément chimique de numéro atomique 37, de symbole Rb. C'est un métal alcalin, mou et argenté, dont la température de fusion n'est que de 39,3 °C. Il peut être maintenu liquide à température ambiante grâce au phénomène de surfusion, comme le césium et le gallium. Son nom vient du latin rubidus (rouge foncé), du fait de la couleur rouge des raies spectrales qui ont permis à Robert Wilhelm Bunsen et Gustav Kirchhoff de le détecter en 1861 dans la lépidolite. Il a été isolé l'année suivante par Bunsen. Comme les autres métaux alcalins, il s'enflamme spontanément au contact avec l'air et réagit violemment avec l'eau.
