1,2-Dioxin adalah senyawa heterosiklik, organik, antiaromatik dengan rumus kimia C₄H₄O₂. merupakan isomer dari 1,4-dioxin (atau p-dioxin).

Mengingat karakteristiknya yang mirip peroksida, 1,2-dioxin sangat tidak stabil dan belum berhasil diisolasi. Bahkan derivat penggantinya juga sangat labil, misal 1,4-difenil-2,3-benzodioxin.^[2] Pada tahun 1990, 3,6-bis(p-tolyl)-1,2-dioxin salah diakui sebagai derivat pertama yang stabil.^[3] Akhirnya diketahui bahwa senyawa tersebut bukan derivat dari 1,2-dioxin, tetapi secara termodinamika lebih stabil daripada dione.^[4]
