Method: This cross-sectional study consisted of 6000 pregnant women who enrolled at the obstetric polyclinic of a state hospital. 638 pregnant women were selected using a random sampling method. The data were collected between April and June 2016 using a data collection form and the Oxford Happiness Scale. In evaluating the data absolute number, percentage, mean, standard deviation, T-test and ANOVA test were employed. Findings:The mean age for the pregnant women was 27.55 ± 5.33 and the mean score on the Oxford Happiness Scale was 122.54 ± 17.18. In this study, there were significant differences observed in age during pregnancy, education level and the gender of child desired by the womens' partners and consequent happiness scores. Result:The pregnant women were found to be moderately happy on average. Young age of the pregnant woman, being highly educated, and the partner having expressed no choice in the sex of the child was associated with an increase in the level of women's happiness. Healthcare staff have a duty to educate society about gender equality.
