Introduction: Maternal mortality remains a major public health problem, particularly in Chad. The aim of this study was to analyse the factors associated with maternal death.
 Method: This was a retrospective descriptive and analytical study conducted at Bongor Provincial Hospital (BPH) over a 5-year period (2015 to 2020). The study population consisted of all maternity patients who died in this hospital and whose records were complete. The variables studied were epidemiological, clinical, and therapeutic factors. The data were collected and analysed using Sphinx Plus²(V5) software. The Chi-square test was used to compare the variables. A p-value of less than 0.05 was considered significant.
 Results: We registered 13,758 women with all pathologies, of which 6,349 met the inclusion criteria; 98 of them died (1.5%) giving a Maternal Mortality Rate (MMR) of 1005/100,000 live births. These deaths mainly occurred in women aged between 20 and 24 years (30.6%), who were married (79.6%), housewives (59.2%), multiparous (33.7%), from rural areas (74.5%), uneducated (39.8%) and who had had no prenatal care (60.2%). The main aetiologies reported were: genital haemorrhage (77.5%), infections (63.3%), malaria (61.2%), severe anaemia (39.8%) and dystocia (25.5%).
 Conclusion: Maternal mortality is a major health problem, and its reduction requires the mobilization of all actors in society and implies good health education, improvement of the quality of prenatal follow-up and emergency obstetric care.
