Psychologist Day is observed in Ukraine every April 23, celebrating the contributions of psychologists and therapists within the country. Although it is not an official professional holiday, it has been widely recognized since 2004 by various professional associations, educational institutions, and organizations employing psychologists, such as schools and government agencies. The day honors the historical development of psychology in Ukraine, tracing its roots back to influential figures like Wilhelm Wundt and prominent Ukrainian psychologists such as Grygoriy Kostiuk and Petro Zinchenko. The National Psychological Association of Ukraine plays a key role in representing the profession and is affiliated with the European Federation of Psychological Associations. Celebrations typically include events organized by professional associations and educational institutions that emphasize the importance of psychological practice and education.
