Dusík je chemický prvok v Periodickej tabuľke prvkov, ktorý má značku N a protónové číslo 7. Je to plyn bez farby a zápachu. Nezávisle od seba ho v roku 1772 objavili Daniel Rutherford a Henry Cavendish a nazvali ho jedovatým vzduchom. Antoine Lavoisier zistil, že tento plyn je zložkou vzduchu a pretože sa v ňom živé organizmy dusili, pomenoval ho azote. Slovenský názov pochádza od prírodovedca J. Presla, ktorý preniesol v roku 1828 francúzsky názov. Medzinárodný názov nitrogenium vznikol z latinského nitrium, ktorým sa označovali chemikálie z popola rastlín. V potravinárstve sa označuje E941.
