Abstract Background Intracerebral hemorrhage (ICH) is associated with a poor prognosis. The association between the neutrophil-to-albumin ratio (NAR) with mortality in patients with ICH remains underexplored. This study investigated the relationship between the NAR and mortality in patients with ICH. Methods A multicenter retrospective observational cohort study was conducted from January 2010 to June 2019. Participants were divided into four groups according to NAR quartiles at admission. Univariable and multivariable logistic regression analyses were used to evaluate the relationship between NAR and 90-day mortality. The predictive power of NAR was compared with neutrophil count and albumin levels using receiver operating characteristic (ROC) curve analysis. Results Patients in the highest NAR quartile had significantly greater odds of 90-day mortality (adjusted OR 1.74, 95% CI 1.27–2.39, p
