Aktinium(III) fluorida (AcF3) adalah sebuah senyawa anorganik, garam dari aktinium dan fluorin.

Aktinium fluorida dapat dibuat dalam larutan atau melalui reaksi padatan. Pada metode pertama, aktinium hidroksida direaksikan dengan asam fluorida, kemudian produk akan mengendap:[3]

Dalam reaksi padatan, logam aktinium direaksikan dengan gas hidrogen fluorida pada suhu 700 °C dalam krus platina.[4][5]

Aktinium fluorida adalah padatan putih yang bereaksi dengan amonia pada suhu 900–1000 °C untuk menghasilkan aktinium oksifluorida:

Lantanum oksifluorida mudah dibentuk dengan memanaskan lantanum fluorida di udara, sementara perlakuan serupa hanya akan meleburkan aktinium fluorida dan tidak menghasilkan AcOF.[4][5]
