Background: Reducing the global Maternal Mortality Ratio to less than 70 per 1,00,000 live births is the first target of Sustainable Development Goal-3. Adequate utilization of Maternal and Child Health (MCH) services is essential for improved maternal and neonatal health outcomes. The utilization of MCH services is a complicated phenomenon, and several factors have an impact on it. This study aims to assess the current status of utilization of antenatal, intranatal, and postnatal maternal health services and determinants of utilization. Methods: This cross-sectional study was conducted in an urban slum during 1st January and February 2020 using a pre-tested, semi-structured questionnaire. A total of 126 women who delivered after 1st January 2018 were included as study subjects after getting informed oral consent. Data entry and analysis were done in Microsoft Excel. P-value<0.05 was considered statistically significant. Result: In all, 64% of study subjects had adequate Antenatal care (ANC) services utilization. The majority (94.5%) had institutional delivery. In all, 62% of women breastfed their child within four hours after birth. The reason for inadequate utilization was mainly due to lack of unawareness of MCH services. Conclusion: Overall, MCH services are good in this area. Efforts should be made to improve the quality of services for ANC registration within first trimester, Iron and Folic Acid tablet consumption, initiation of early breastfeeding, and postnatal care services, and the major determinants that influence utilization of MCH services including mother's education and parity
