Neonatal jaundice (NNJ) is a cause of neonatal morbidity and mortality. Previous intervention studies on NNJ focused on increasing the knowledge of mothers and not improving the health-seeking behaviour of the mothers.  Therefore, this study evaluated the effect of educational intervention on health-seeking behaviour regarding NNJ among pregnant mothers in selected antenatal clinics in Ilorin, Kwara State, Nigeria. Quasi-experimental research design was employed for this study. Eight Primary Health Centres (PHC) with the highest patronage formed the study population of 1368 pregnant women. A sample of 128 was determined using the power formula and systematic sampling technique was used to select 16 participants from each PHC. Data were collected using questionnaire at baseline, immediate post-intervention, and 8th week follow-up.  Findings showed that there was significant difference (p < 0.05) in the mean score of health-seeking behaviour of NNJ between baseline for the Intervention Group (IG) (8.28 ± 2.11) and 8th week follow-up (10.82 ± 1.28), but there was no significant difference (p > 0.05) in the health-seeking behaviour of NNJ for the Control Group (CG) between baseline (7.80 ± 2.07), and 8th week follow-up (7.80 ± 2.07). IG had an Effect Size (ES) of -1.47 (-1.77 to -1.17) for the health seeking behaviour. The study concluded that educational intervention improved the health-seeking behaviour of pregnant women attending antenatal clinic in Ilorin, Kwara State, Nigeria. This study recommended that primary health centres should implement a routine health educational program towards improving the health-seeking behaviour of pregnant women regarding neonatal jaundice.
