Abstract Background This study focused on the relationship between the neutrophil‐to‐lymphocyte ratio (NLR) and the dose of organs at risk in patients with stage II–III non‐small cell lung cancer (NSCLC) receiving intensity‐modulated radiotherapy. Methods The clinical characteristics and dosimetric parameters of 372 patients were collected retrospectively. A high NLR was defined as that ≥1.525. Survival analysis was conducted using the Kaplan–Meier and Cox regression analysis. Least absolute shrinkage and selection operator (LASSO) analysis was conducted to select appropriate dosimetric parameters. The risk factors of NLR were evaluated using univariate and multivariate logistic regression analyses. Results Patients with a high NLR had poorer progression‐free survival (PFS) (p = 0.011) and overall survival (OS) (p = 0.061). A low NLR (
