Objective: This study aims to determine the relationship between nutritional status and the incidence of acute respiratory infections (ARI) in toddlers. Method: This study was conducted with observational analytic method with cross sectional approach. Results: The results of this study showed that toddler patients with ARI in Tongas Probolinggo Hospital were dominated by female patients (51.7%), male patients (48.3%). The age of patients who dominated is age 1-2 years (60.0%) and 3-4 years (40.0%). The types of patients based on nutritional status were well-nourished patients (53.3%) undernourished (26.7%) and malnourished 12 people (20.0%). Diagnosis of the disease Non-ARI (33.3%) and ARI (66.7%). The data results using the chi square method showed a p value of 0.001 < α = 0.05, so it can be concluded that H0 is rejected, H1 is accepted.
