O oganésson (português europeu) ou oganessônio (português brasileiro) (previamente chamado de ununóctio) é o elemento químico superpesado sintético de número atômico 118 (118 prótons e 118 elétrons), de símbolo químico Og. Ocupa o grupo 18 (VIIIA ou 0) da tabela periódica juntamente com os gases nobres. Em 2015, a IUPAC e a IUPAP confirmaram descoberta dos elementos nipónio, moscóvio, tenesso e o oganésson. A designação (em inglês) foi oficializada pela IUPAC em 28 de novembro de 2016 como oganesson - referência ao físico nuclear russo Yuri Oganessian.
