ルビジウム（ラテン語: rubidium 英語発音: [rʉˈbɪdiəm]）は原子番号 37 の元素記号 Rb で表される元素である。アルカリ金属元素の1つで、柔らかい銀白色の典型元素であり、原子量は85.4678。ルビジウム単体は、例えば空気中で急速に酸化されるなど非常に反応性が高く、他のアルカリ金属に似た特性を有している。ルビジウムの安定同位体は 85Rb ただ1つのみである。自然界に存在するルビジウムのおよそ28%を占める同位体の 87Rb は放射能を有しており、半減期はおよそ490億年である。この半減期の長さは、推定された宇宙の年齢の3倍以上の長さである。 1861年に、ドイツの化学者ロベルト・ブンゼンとグスタフ・キルヒホフが新しく開発されたによってルビジウムを発見した。ルビジウムの化合物は化学および電子の分野で利用されている。金属ルビジウムは容易に気化し、利用しやすいスペクトルの吸収域を有しているため、原子のレーザ操作のための標的としてしばしば用いられる。ルビジウムの生体に対する必要性は知られていない。しかし、ルビジウムイオンはセシウムのように、カリウムイオンと類似した方法で植物や生きた動物の細胞によって活発に取り込まれる。
