'''氧化亚铊'''是一种[[无机化合物]]，由[[铊]]和[[氧]]组成，化学式Tl<sub>2</sub>O。在这种化合物里，铊拥有+1 [[氧化态]]。在水里，氧化亚铊会生成[[碱性]]，黄色的[[氢氧化亚铊]] (TlOH)。氧化亚铊用来制作高[[反射度]]的[[玻璃]]。氧化亚铊和[[酸]]反应，形成铊盐。

氧化亚铊和其他铊化合物一样，都有剧毒。

== 制备 ==
氧化亚铊可以由[[氢氧化亚铊]]在100&nbsp;°C下分解或是[[氧化铊]]隔绝空气加热到700&nbsp;°C而成。<ref name="Simon Aldridge, Anthony J. Downs">{{cite book | last=Aldridge | first=S. | last2=Downs | first2=A.
