Abstract: Background: Insomnia is a common sleep problem among college students. There is insufficient research on the inter-relationships between different insomnia symptoms and their associated factors and quality of life (QoL). This study examined the prevalence and correlates of insomnia symptoms (insomnia hereafter) among Chinese college students as well as their association with QoL from a network perspective. Methods: A multi-center, cross-sectional study was conducted between September and December 2023 in China. Insomnia symptoms were assessed using Insomnia Severity Index (ISI). The centrality index of “Expected influence†was applied to identify the most central symptoms in the network, and the “flow†function was used to identify specific symptoms that were directly related to QoL. Results: The prevalence of insomnia among the 6,514 college students was 26.42% ( n  = 1,721; 95% confidence interval [95% CI] [25.17, 27.67%]). The logistic regression analysis revealed that having a history of psychiatric problems (odds ratio [OR] = 1.316, p  = .003), being quarantined during the COVID-19 pandemic (OR = 1.134, p  = .035), and currently smoking (OR = 1.431, p  = .005) and drinking (OR = 1.386, p
