Tetrabutylammonium tribromide is a pale orange solid with the formula [N(C₄H₉)₄]Br₃. It is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. The salt is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine.

The compound is prepared by treatment of solid tetrabutylammonium bromide with bromine vapor:^[2]

[N(C₄H₉)₄]Br + Br₂ → [N(C₄H₉)₄]Br₃
