(1) Background: Nurses are exposed to occupational stressors that may impair their well-being and quality of life. This study examined whether burnout and secondary traumatic stress mediate the relationship between perceived stress and physical and psychological quality of life. (2) Methods: A cross-sectional study included 294 nurses employed at the Clinical Hospital Center Osijek, Croatia. Data were collected using the Perceived Stress Scale (PSS-10), the Burnout and Secondary Traumatic Stress subscales of the Professional Quality of Life Scale (ProQOL-5), and the physical and psychological domains of the WHOQOL-BREF. Pearson correlations and path analysis were used. (3) Results: Perceived stress showed significant negative effects on physical (β = −0.291; p < 0.001) and psychological quality of life (β = −0.217; p < 0.001), and positive effects on burnout (β = 0.230; p < 0.001) and secondary traumatic stress (β = 0.171; p = 0.002). Burnout significantly mediated both relationships, while secondary traumatic stress did not. The model explained 20.8% and 19.3% of variance in physical and psychological quality of life. (4) Conclusions: Burnout represents an important pathway linking perceived stress with poorer quality of life among nurses.
