Hypertension (HTN) is an important risk factor for cardiovascular disease (CVD) mortality and morbidity among Iranians. The present study aimed to estimate the prevalence of pre-HTN and HTN and some of its related factors in south of Iran. This cross-sectional survey was conducted on the data of the Persian cohort study in Kherameh. The participants consisted of 10,663 people aged 40–70 years. HTN was defined as either systolic/diastolic blood pressure (SBP/DBP) ≥140/90 mmHg or taking medications. Pre-HTN was defined as SBP = 120–139 mmHg and/or DBP = 80–89 mmHg. The logistic regression method was used to identify the factors associated with pre-HTN and HTN. The age-standardized prevalence rate (ASPR) of pre-HTN was 19.66% (95% CI: 19.45–19.86%) and 18.59% (95% CI: 18.36–18.83%) in males and females, respectively. Also, the ASPR of HTN was 21.44 (95% CI: 21.22–21.65%) in males and 33.53% (95% CI: 33.22–33.85%) in females. Male gender, old age, being unemployed, low education level, high body mass index (BMI), no smoking, diabetes, cerebro-cardiovascular disease, suffering from another chronic disease, family history of CVD, and negative family history of cancer and other chronic diseases were independently associated with pre-HTN (
p
 < 0.05). All variables, except for gender, smoking, and family history of cancer, were significantly associated with HTN. Drug abuse was also correlated to HTN (
p
 < 0.05). This study revealed the increased prevalence of HTN in rural and urban areas. Therefore, the health system needs to develop strategies to raise the accessibility of screening and diagnostic services.
