In this article we study the class of mappings in indefinite inner product spaces which preserve orthogonality. We derive characterization of orthogonality preserving mappings in indefinite inner product spaces which is a generalization of characterization of orthogonality preserving mappings in inner product spaces proposed by Chmielinski [J. Chmielinski, J. Math. Anal. Appl., \(\textbf{304}\) (2005), 158--169].
