'''Tidur gelombang lambat''' ({{lang-en|slow-wave sleep}}, disingkat '''SWS'''), sering juga disebut '''tidur nyenyak''', merupakan tahap tiga pada [[tidur non-REM]] (''non-rapid eye movement'').<ref>{{cite book |last=Rechtschaffen |first=A |author2=Kales, A |title=A Manual of Standardized Terminology, Techniques and Scoring System For Sleep Stages of Human Subjects |publisher=US Dept of Health, Education, and Welfare; National Institutes of Health |year=1968}}</ref> Pada awalnya, tidur gelombang lambat mencakup tahap 3 (dengan 20-50 persen [[gelombang delta|aktivitas gelombang delta]]) dan tahap 4 (dengan lebih dari 50% gelombang delta).<ref>Carlson, Neil R.
