We conducted a scoping review to synthesize the current evidence of the association between experiences of violence and sleep in women. <b>Methods</b> Between August and October 2023, we conducted a search in four databases (PubMed, APA PsycInfo, Embase, and Web of Science) for peer-reviewed articles, using 11 inclusion and exclusion criteria. Any study published in English in peer-reviewed journals that conducted original research on the association between exposure to violence (lifetime IPV, IPV during the previous year, during and 1 year after pregnancy, as well as adverse childhood experiences) and poor sleep outcomes (sleep disturbances, insomnia, poor sleep quality, and longer time to fall asleep) in the perinatal population were included. <b>Results</b> The synthesis of the 12 included studies revealed a positive association between exposure to violence and poor sleep, and between adverse childhood experiences and sleep disturbances or poor sleep during pregnancy.

However, it is evident that the experience of violence throughout life is a risk for poor perinatal sleep quality.
