In the title molecular salt, C15H17N 2O+·Br-, the benzene and pyridinium rings form a dihedral angle of 83.0 (1)°. In the crystal, N - H⋯Br and N - H⋯O hydrogen bonds link the components into chains along [010]. These chains are linked by weak C - H⋯O and C - H⋯Br hydrogen bonds, forming a three-dimensional network.
