Ending the epidemics of malaria for quality livelihood is well addresses in the 2030 Agenda for Sustainable Development and in the 2025 Development Vision. Recently, Malaria in pregnancy is still drawing much attention in most African countries, due to its contribution to devastating maternal and neonatal outcomes. The use of an insecticide-treated net is identified as providing approximately eighty per cent protection against malaria attack and is one of the recommended vector control approaches for the prevention of malaria in pregnancy. It is for this reason that, the study examined the determinants of Insecticide Treated Nets utilisation among pregnant women in Tanzania. The logit model was used to uncover the determinants of ITN utilisation among pregnant women. Results showed that access to ITN, number of previous pregnancies, knowledge that malaria can be prevented using ITN, education level and household wealth were significant predictors of ITN utilisation. The study recommends that there should be the redistribution of ITN to households with no nets and those with untreated nets. This should be accompanied by behaviour change and communication interventions to pregnant women, their husbands, and the entire community in general.
