This paper presents a study to investigate the relationship between organizational culture and communication apprehension among some employees who worked for Iran broadcasting channel. The study has adopted two well-known questionnaires developed by Hofstede (1984) [Hofstede, G. (1984). Culture & apos; s Consequences: International Differences in Work-Related Values (2nd ed.). Beverly Hills CA: SAGE Publications. ISBN 0-8039-1444-X] for organizational culture and McCroskey et al. (1985) [McCroskey, J. C., Beatty, M. J., Kearney, P., & Plax, T. G. (1985). The content validity of the PRCA?24 as a measure of communication apprehension across communication contexts. Communication Quarterly, 33(3), 165-173.] for communication apprehension (CA). We have used Chi-Square test to verify different hypotheses of the survey and the results of the survey have indicated that while there was no relationship between CA and three components including cultures of masculinity, individualistic culture and ambiguity aversion, there was a significance relationship between CA and power distance. The results of our survey indicate that as the power distance increases we may expect a higher level on CA.
