Tin(IV) bromide is the chemical compound SnBr₄. It is a colourless low melting solid. SnBr₄ can be prepared by reaction of the elements at normal temperatures:

In aqueous solution Sn(H₂O)₆⁴⁺ is the principal ionic species amongst a range of 6 coordinate ions with from 0-6 bromide ligands (e.g. Sn(H₂O)₆⁴⁺, SnBr(H₂O)₅³⁺) In basic solution the Sn(OH)₆²⁻ ion is present.
SnBr₄ forms 1:1 and 1:2 complexes with ligands, e.g. with trimethylphosphine the following can be produced, SnBr₄.P(CH₃)₃ and SnBr₄.2P(CH₃)₃.
SnBr₄ crystallises in a monoclinic form with molecular SnBr₄ units that have distorted tetrahedral geometry.
