The professional practice of the psychologist in organizations is essential in addressing the problems of the relationship between the individual and work. This research aimed to describe the competencies, functions and areas of action of psychologists working in the organizational context. A questionnaire designed for the research was applied to 62 psychologists belonging to 45 companies in Neiva (Colombia) selected under non- robabilistic criteria for convenience. The results show that the participants work mostly in private sector companies whose economic activity is to offer administrative and support services. They affirm being more competent in knowledge, attitudes, ethical values, professional development, as well as in knowing, arguing and applying concepts of organizational psychology. The results indicate that the most performed functions by psychologists are to prepare and present reports orally and in writing, to promote the organizational climate, to work in interdisciplinary teams and to train the staff. Relocating employees within the organization, supporting the definition of salary policies and recognition of merits, and conducting research processes are among the lowest performing functions.
