**三氯化鉈**是一種無機化合物，是鉈的氯化物之一，化學式為 TlCl3。

## 製備

三氯化鉈的四水合物可由氯化亞鉈在水中和氯氣反應得到：

　
: $\mathrm {TlCl+Cl_{2}+4\ H_{2}O\longrightarrow TlCl_{3}\cdot 4\ H_{2}O} $

水合物直接脫水會分解為氯化亞鉈，但在氯氣的存在下和氯化亞碸或光氣反應，可以得到無水物：

　
: $\mathrm {TlCl_{3}\cdot 4\ H_{2}O+4\ SOCl_{2}\longrightarrow TlCl_{3}+4\ SO_{2}+8\ HCl} $

　
: $\mathrm {TlCl_{3}\cdot 4\ H_{2}O+4\ COCl_{2}\longrightarrow TlCl_{3}+4\ CO_{2}+8\ HCl} $

它也可由亞硝醯氯和鉈反應，經 TlCl3・NOCl 中間體，減壓使之分解得到：

　
: $\mathrm {3\ NOCl+Tl\longrightarrow TlCl_{3}+3\ NO} $
