Objectives: This study aims to determine the prevalence, and associated factors of undiagnosed hypertension [Systolic Diastolic Hypertension (SDH), Isolated Systolic Hypertension (ISH) and Isolated Diastolic Hypertension (IDH)] in the Nepalese adult population. Methods: Nepal Demographic and Health Survey 2016 data from adults (≥ 18 years) was used in this study. The final weighted sample size was 13,393. Blood pressure (BP) was measured 3 times and the average of the second and third measurement was reported. SDH (systolic BP (SBP) ≥ 140 mmHg and diastolic BP (DBP) ≥ 90 mmHg), ISH (SBP ≥ 140 mmHg and DBP \u3c 90 mmHg), and IDH (SBP \u3c 140 mmHg and DBP ≥ 90 mmHg) were measured. Multilevel logistic regression analyses were conducted to find the association between the independent variables and the covariates. Results: The prevalence of SDH, IDH and ISH were 8.1%, 7.5%, and 3.3% respectively. The odds of having SDH and ISH increased with old age. However, the odds of having IDH decreased with increasing age. Females has lower odds of having SDH and IDH compared with male participants. Individuals that had been married, resided in Province 4 (p \u3c 0.05) or 5 (p \u3c 0.01) were statistically significantly associated with having IDH. Being overweight or obese was statistically significantly associated with all 3 HTN subtypes (p \u3c 0.001). Conclusion: The necessary steps should be taken so that public health promotion programs in Nepal may prevent and control undiagnosed hypertension
