1,4-Dioxane () is a heterocyclic organic compound, classified as an ether. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether. The compound is often called simply dioxane because the other dioxane isomers (1,2- and 1,3-) are rarely encountered.

1,4-二噁烷（英語：1,4-dioxane），透明無色的单环雜環有機化合物，在室溫下為液體，有輕微類似乙醚的清香氣味，是常用的非质子溶剂。分子式為 C4H8O2，沸點為 101 °C，可与水和常见有机溶剂混溶，有潮解性。 二噁烷的极性比乙醚强，熔点也比乙醚高。溶解能力较强，强于四氢呋喃，与二甲基甲酰胺相近。无水时容易生成爆炸性的过氧化物，蒸馏会使过氧化物的浓度增大，造成危险。
