Sleep complaints are prevalent and associated with poor health‐related quality of life (HRQoL), depression and possibly mortality in dialysis patients. This study aimed to explore possible associations between sleep quality, daytime sleepiness and mortality in dialysis patients. In this study, 301 dialysis patients were followed up to 4.3 years. HRQoL was evaluated at baseline with the Kidney Disease and Quality of Life—Short Form (KDQoL‐SF), depression with Beck Depression Inventory (BDI), sleep quality with Pittsburgh Sleep Quality Index and daytime sleepiness with Epworth Sleepiness Scale. The single item “on a scale from 0–10, how would you evaluate your sleep?” in the sleep subscale in KDQoL‐SF was used to identify poor (0–5) and good sleepers (6–10). A total of 160 patients (53.3%) were characterized as poor sleepers. They were younger (r = 0.241, P
