In this article three generations of research addressing the marketing construct in nonprofit organizations are critically analyzed: (a) market orientation in nonprofit organizations, (b) societal orientation, and (c) research contributions aiming to close the existing practice–theory gap on this topic. A qualitative study among 24 nonprofit marketers is conducted in Canada and Germany to develop a construct labeled nonprofit marketing orientation. It includes the dimensions of brand orientation, supporters’ orientation, commercial orientation, and service orientation. Furthermore, the authors describe the nomological net of nonprofit marketing orientation to present interconstruct relationships and to inform future research.
