'''Oksigen triplet''' (''<sup>3</sup>''O<sub>2</sub>) adalah oksigen dengan [[keadaan tingkat dasar]] ''S'' = 1. Oksigen triplet merupakan [[alotropi|alotrop]] [[alotrop oksigen|oksigen]] yang paling stabil dan paling banyak ditemui. Menurut [[teori orbital molekul]], [[konfigurasi elektron]] oksigen triplet terdiri dari dua elektron yang menduduki dua [[orbital molekul]] π<sub>g</sub> dengan energi yang setara. Sesuai dengan [[kaidah Hund]], elektron-elektron ini tidak berpasangan. Orbital yang baru diisi setengah ini bersifat [[antibonding]] dan mengurangi jumlah ikatan molekul dari nilai maksimal 3 menjadi 2.

Lambang oksigen triplet dalam [[notasi spektroskopi]] adalah <sup>3</sup>Σ{{su|b=g|p=−}}.<ref>Atkins, Peter; De Paula, Julio; Friedman, Ronald (2009) ''Quanta, Matter, and Change: A Molecular Approach to Physical Chemistry,'' hlm. 341–342, Oxford: Oxford University Press, {{ISBN|0199206066}}, see [https://books.google.com/books?isbn=0199206066]. accessed 11 August 2015.</ref>
