Plutonium(III) chloride is the chemical compound with the formula PuCl₃. It can be prepared by dissolving the metal in hydrochloric acid.

Plutonium atoms in crystalline PuCl₃ are 9 coordinate, and the structure is tricapped trigonal prismatic.

As with all plutonium compounds, it is subject to control under the Nuclear Non-Proliferation Treaty. Due to the radioactivity of plutonium, all of its compounds, PuCl₃ included, are warm to the touch. Such contact is not recommended, since touching the material may result in serious injury.
