Background Maternal mortality represents the health condition of the mother during pregnancy. In developing countries, maternal health is often poor because pregnant women are not fully supported by their husbands. The problem is, husbands have cultural barriers to engage in activities that can provide space for pregnant women to be healthier.   Aim This study was conducted to examine the husband's cultural barriers in the Toba Batak culture in North Sumatra, Indonesia.   Methods The research was conducted using a qualitative approach in rural areas. A total of 30 husbands were interviewed using FGD techniques, in addition to FGDs with health workers.   Results This study reveals the root of cultural problems related to the husband's perception of men's and women's work, as well as the inherent traditions that make the husband distance himself from maternal health.   Conclusion Cultural barriers of husband’s involvement in maternal health are very clear in Batak tribe. Efforts are needed to change cultural barrier by implementing a cultural approach.
