The purpose of this study is to investigate factors influencing marital satisfaction among Christian wives in South Korea. It was hypothesized that marital satisfaction among Christian wives could be predicted from income, educational level, spouse\'s occupation, the number of years of marriage, decision making, division of household tasks, relationship with current family, relationship with spouse’s family, communication problems, and sexual satisfaction. The study used a number of existing measures. These included Index of Sexual Satisfaction, Task Participation Index, Decision Power Index, Conjugal Understanding Measure, and the Kansas Marital Satisfaction. Additionally, other more general demographic information was gathered including respondent\'s income, religion, educational background, the number of years of marriage, husband\'s occupation, relationship with spouse\'s family and relationship with current family. The present study collected data from Christian wives in South Korea. Using snowball, purposeful and convenient sampling methods, a sample of 370 Christian wives completed survey. Multiple regression analyses indicated that sexual satisfaction, conjugal communication, relationship with spouse’s family and relationship with current family were significantly associated with marital satisfaction among the Christian wives, explaining 50.4% of the variance in the marital satisfaction score. Sexual satisfaction was the best predictor of marital satisfaction and accounted for 36.4% of the variance in marital satisfaction among Christian wives. The second most important predictor of marital satisfaction among the Christian wives was conjugal communication and explained 8.9% of variance. The relationship with spouse\'s family was the third significant variable to account for the variance of marital satisfaction among the Christian wives and explained 4.1% of the variance. As the least predictor, the relationship with current family accounted for 1.1% of the variance of the marital satisfaction among the Christian wives. The findings of the present study suggest several implications for future research. One principal finding was the important role of sexual satisfaction in marital satisfaction among the Christian wives. Future studies might explore this factor further. This study found the importance of conjugal communication in marital satisfaction among the Christian wives. This result suggests the importance of enhancing couples\' skills in direct negotiation and decision making. Therefore, Christian couples need to learn conjugal communication skills to enhance their marital relationships with spouses. The findings of the study revealed the significance of relationship with spouse\'s and wives\' family in the degree of marital satisfaction.
